Designing for Print on Demand: File Prep, Color, and Materials That Sell

You spent hours on your sticker design. The colors are perfect on screen. Every line is crisp. Every detail is exactly where you want it. You upload the file, wait for your sample order, and—what happened? The colors look flat. There's a thin white edge where there shouldn't be one. That tiny text you painstakingly placed? It's a blurry smudge.

If this has happened to you, you're not alone. It happens to almost everyone who's new to print on demand. The gap between "looks great on my screen" and "looks great in my hand" is real, and it catches people off guard every single time.

The good news? That gap is entirely predictable and entirely preventable. Designing for print isn't about being a better artist—it's about understanding how your digital file becomes a physical object, and preparing your work accordingly. Once you know the rules, they become second nature.

This guide covers everything: file formats, color management, bleed zones, material-specific tricks, and the pre-flight checklist we use at The Potato Club before we print anything. By the end, you'll never have a "what happened to my colors?" moment again.

Part 4 of The Print on Demand Playbook — a 14-part series on building a successful custom print business. Catch up on Part 1: What Is Print on Demand?, Part 3: Starting a POD Business, or skip ahead to Part 5: Pricing Your POD Products.

Why Design Quality Makes or Breaks POD Success

In Part 1, we talked about how POD works—design, upload, sell, print. But there's a critical detail hidden in that flow: the design file is the product. In traditional manufacturing, you'd approve a physical proof before committing to a production run. In POD, your digital file goes straight from upload to print with minimal human intervention.

That means your file quality directly determines your product quality. Not your artistic skill—your file quality. You can be an incredible illustrator and still produce a mediocre sticker if your resolution is wrong, your colors aren't calibrated, or you forgot to add bleed.

This matters because in the POD sticker market, quality is your competitive advantage. Customers can't hold your product before they buy. They're making a decision based on a photo and a review. If the physical product doesn't match the listing image—if the colors are dull, the cut is off-center, or the detail is lost—you get a bad review, a refund, and a customer who never comes back.

Conversely, when your print quality is sharp, colors are vibrant, and the cut is clean, people notice. They photograph it. They post it. They come back for more. Good file prep isn't just a technical step. It's a business strategy.

Understanding the Print Process: From Screen to Sticker

Before we get into specifications, let's walk through what actually happens to your file. Understanding the process makes every guideline in this guide make sense.

Step 1: Your Digital File Is Received

Your PNG, SVG, or PDF arrives in our production queue. The first thing we check is resolution and color mode. If the file is too low-resolution, we flag it—not to be difficult, but because we'd rather tell you upfront than send you a blurry sticker.

Step 2: Color Conversion Happens

Your screen displays color in RGB (red, green, blue light). Our printers lay down ink in CMYK (cyan, magenta, yellow, black). Your file gets converted from one color space to the other. This conversion isn't always 1:1—some RGB colors simply don't exist in CMYK ink. We'll cover this in depth shortly.

Step 3: The Design Is Printed

Your design is printed onto vinyl or paper stock using high-resolution digital printers. The ink is laid down in tiny dots—so small they're invisible to the naked eye—that combine to create every color in your design.

Step 4: Lamination (If Applicable)

For vinyl stickers, a protective laminate is applied over the print. This can be matte, gloss, or holographic. The laminate changes how colors appear: matte softens, gloss deepens, holographic shifts. We'll discuss how to design for each.

Step 5: Cutting

A cutting machine reads the cut path (the outline of your sticker) and cuts through the material. For die-cut stickers, it cuts all the way through. For kiss-cut stickers, it cuts only the top layer, leaving the backing intact. Sticker sheets have multiple kiss-cuts on one backing sheet.

Step 6: Quality Check and Shipping

The finished product is checked, packed, and shipped. In Singapore and internationally, as we covered in Part 3.

Every step in this process is an opportunity for your design to shine—or to fall flat. The rest of this guide is about making sure it shines.

File Format Essentials

Let's get into the technical foundation. This is the stuff that separates "it printed okay" from "it printed perfectly."

Vector vs. Raster: When to Use Each

Raster images are made of pixels. Think photos, digital paintings, Procreate files, anything from Photoshop. They have a fixed resolution—zoom in enough and you'll see individual squares.

Vector graphics are made of mathematical paths. Think logos, typography, line art, anything from Illustrator or Inkscape. They scale infinitely without losing quality.

For stickers, both have their place:

Use Raster When Use Vector When
Hand-drawn illustrations Logos and branding
Painted/brushed textures Typography-heavy designs
Photo-based designs Simple shapes and icons
Gradients and complex shading Line art
Procreate artwork Patterns and geometric designs

The key insight: start in whatever medium feels natural, but deliver in the right format. If you draw in Procreate (raster), export at maximum resolution. If you design in Illustrator (vector), you're already in great shape.

Recommended Formats

PNG (with transparent background) — This is the gold standard for sticker files. PNG supports transparency (essential for die-cut stickers), maintains quality, and is universally accepted by POD platforms.

SVG — Ideal for vector designs. Infinitely scalable, small file sizes, and the cut path is often embedded directly in the file. Perfect for simple to moderate complexity designs.

PDF — Excellent for complex designs with both vector and raster elements. Maintains quality across platforms and preserves color information well.

High-resolution JPG — Acceptable for rectangular designs where transparency isn't needed (like sticker sheets with a full printed background). Not suitable for die-cut stickers with custom shapes.

Resolution Requirements

300 DPI (dots per inch) at actual print size. This isn't a suggestion—it's the minimum for sharp, professional results.

What does this mean in practice? If your sticker is 3 inches × 3 inches, your file should be at least 900 × 900 pixels. Here's a quick reference:

Sticker Size Minimum Pixels (at 300 DPI)
2" × 2" 600 × 600 px
3" × 3" 900 × 900 px
4" × 4" 1,200 × 1,200 px
5" × 3" 1,500 × 900 px
6" × 4" 1,800 × 1,200 px
8" × 3" 2,400 × 900 px

Pro tip: Always design larger than you need. A 600 DPI file scaled down looks better than a 150 DPI file scaled up. You can always shrink a file; you can't magically add detail that wasn't there.

File Size Considerations

Most POD platforms have file upload limits. Keep your files under 25MB when possible. For very detailed designs, this means:

  • Flatten layers before exporting (unless layers are needed for cut paths)
  • Remove hidden layers and unused assets
  • Use PNG compression—it's lossless, so quality is preserved
  • For vector files, simplify overly complex paths

Color Management: The RGB-to-CMYK Gap

This is the single biggest source of disappointment for new POD sellers. Let's break it down clearly.

RGB vs. CMYK: What's Actually Happening

Your monitor creates color by combining red, green, and blue light. It's additive—more light means brighter colors. A screen can display roughly 16.7 million colors in the RGB color space.

A printer creates color by combining cyan, magenta, yellow, and black ink. It's subtractive—ink absorbs light. CMYK can reproduce a much smaller range of colors than RGB.

The result? Some colors that look stunning on your screen are literally impossible to print with ink.

The Colors That Cause the Most Problems

Neon anything — Neon pink, neon green, electric blue. These exist on screen because they're created by bright, saturated light. Ink cannot reproduce this intensity. What prints as "neon pink" will look more like a saturated magenta.

Bright greens and teals — The green-blue range is where RGB and CMYK diverge most dramatically. That vibrant teal on your monitor will print duller and slightly shifted toward blue.

Deep, rich purples — These tend to shift toward blue or become muddy in print.

Pure, saturated oranges — Often print slightly browner or more muted than expected.

How to Calibrate Your Expectations

You don't need to guess what your colors will look like. Here's how to preview accurately:

  1. Work in CMYK mode if your software supports it. Adobe Illustrator, Photoshop, and InDesign all support CMYK workspaces. When you pick a color in CMYK mode, you're seeing something much closer to the final print result.

  2. Use soft-proofing. Most professional design software has a "proof colors" or "soft proof" feature that simulates CMYK output on your RGB screen. It's not perfect, but it's much closer than designing blind.

  3. Use a CMYK color picker. Online tools like the Pantone Color Bridge or CMYK color charts show you exactly what colors look like in print. Bookmark one and refer to it when choosing your palette.

  4. Order a test print. Nothing replaces seeing your actual design on the actual material. At The Potato Club, our minimum orders start from a single piece—so you can test without committing to volume. It's the best $2 you'll ever spend.

Color Profiles

If you want to get technical (and you should), use the right color profile:

  • For print: Use US Web Coated (SWOP) v2 or FOGRA39 as your CMYK profile
  • For screen/RGB: Use sRGB IEC61966-2.1 as your RGB profile
  • Embed your profile when saving files—this tells the printer exactly how to interpret your colors

Designing for Special Materials: Metallics, Holographic, and More

Special materials add an extra dimension to your designs—but they also require specific design considerations.

Holographic stickers — The holographic effect shifts colors as you move the sticker. Design with this in mind: use bold, simple shapes and avoid large areas of white (white ink covers the holographic effect, making it look flat). Darker colors let the holographic shine through best. Blacks, deep blues, and rich purples look incredible on holographic material.

Metallic materials — Metallic surfaces reflect light and add a premium feel. Your design's dark areas become the metallic areas, and your lighter printed areas sit on top. Use high contrast for maximum impact.

Clear/transparent stickers — These print on transparent vinyl. Any white in your design becomes visible white ink; any transparent area shows through to whatever surface the sticker is applied to. Consider how the sticker will look on both light and dark surfaces—your design needs to work on both.

We'll go deeper into material-specific design later in this guide.

Bleed, Safe Zones, and Cut Lines

This is the technical bit that separates amateur stickers from professional ones. Get this right, and your stickers will always look clean and polished.

What Is Bleed and Why Does It Matter?

Bleed is extra design area that extends beyond the cut line. It exists because cutting isn't pixel-perfect—there's always a tiny margin of variation (usually 1-2mm). Without bleed, a slight cut misalignment would leave a thin white edge on your sticker.

The standard bleed is 3mm (about 1/8 inch) on all sides. If your sticker is 50mm × 50mm, your design file should be at least 56mm × 56mm—extending your background, colors, and any elements that go to the edge by 3mm in every direction.

The Safe Zone

The safe zone is the area inside the cut line where all critical elements should stay. Text, important details, and recognizable features should be inside this zone to ensure they're not affected by cut variation.

Keep text and critical elements at least 3mm inside the cut line. For small stickers (under 2 inches), increase this to 4-5mm because proportional variation is more noticeable at small sizes.

Die-Cut vs. Kiss-Cut Design Considerations

Die-cut stickers are cut all the way through—both the sticker and the backing. The cut line follows the outline of your design (or a simple shape around it). Design considerations:

  • Provide a clear, smooth cut path. Extremely jagged or intricate outlines may not cut cleanly
  • Avoid very thin protruding elements (under 2mm) that could tear
  • Rounded shapes cut more cleanly than sharp angles
  • If your design is rectangular, consider rounded corners—they look more polished and cut more reliably

Kiss-cut stickers are cut only through the top layer, leaving the backing sheet intact. Design considerations:

  • Your cut line needs to be clean and continuous
  • Consider how the sticker will peel off the backing—complex internal cutouts can be tricky
  • Kiss-cut is ideal for sticker sheets where multiple designs share one backing

Sticker sheets combine multiple kiss-cut designs on one sheet. Design considerations:

  • Leave at least 3mm between individual stickers
  • Consider the overall sheet layout—rectangular grids are easier to produce than scattered arrangements
  • Include a margin around the edge of the sheet (at least 5mm)

White Borders vs. Borderless Designs

This is a design choice that also affects production:

White border (recommended for beginners): A 1-3mm white border around your design creates a clean, professional look. It's forgiving of minor cut variations and works with almost any design. Most professional sticker brands use a white border.

Borderless (full bleed): Your design extends to the edge of the sticker. More visually impactful, but requires precise file prep with proper bleed. Any cut variation is more noticeable.

Our recommendation: Start with a white border. It's safer, looks cleaner, and gives you room to learn the production nuances. Move to borderless once you're confident in your file prep.

Material-Specific Design Tips

Every material interacts with ink differently. Designing for the material is just as important as designing for the product.

Vinyl Stickers (from $2.00 SGD)

The default choice and for good reason. Vinyl is durable, waterproof, and works with almost any design style. Colors print vibrantly, details are sharp, and the material handles complex designs well.

Design tips for vinyl:

  • Most versatile material—don't overthink it
  • Colors print true to your CMYK preview
  • Works well for both detailed illustrations and simple graphics
  • Add laminate for extra durability (recommended for stickers that go on laptops, water bottles, cars)

Matte Laminate

Matte laminate softens colors slightly and adds a smooth, non-reflective finish. It has a sophisticated, understated look that works particularly well for:

  • Elegant typography and calligraphy designs
  • Muted, pastel color palettes
  • Nature illustrations and botanical art
  • Designs that need to be written on (planners, journals, labels)

Design tips for matte:

  • Boost saturation 10-15% compared to what looks right on screen, as matte slightly dulls colors
  • Avoid designs that rely on high contrast and shine
  • Test with fine lines—very thin lines can appear softer on matte

Gloss Laminate

Gloss laminate enhances color depth and adds a reflective, eye-catching shine. It's the "pop" finish—colors look richer, blacks look deeper, and the overall effect is bold and attention-grabbing.

Design tips for gloss:

  • Great for bold, colorful designs that need to stand out
  • Dark colors look particularly rich and deep
  • Avoid large solid dark areas if fingerprints are a concern (gloss shows them)
  • Works well for product labels, brand stickers, and anything that needs to catch the eye

Holographic

Holographic material is show-stopping—the surface shifts between rainbow colors as light hits it. But it requires specific design strategies to look its best.

Design tips for holographic:

  • Avoid large areas of white ink. White ink covers the holographic effect. Where you want holographic to show through, keep the design minimal or use dark inks
  • Dark colors (black, navy, deep purple) look stunning because they let the holographic effect shine
  • Simple, bold designs work better than intricate details—the holographic surface can mask fine details
  • Consider designing with the holographic effect as a design element—use it deliberately for backgrounds and highlights
  • Text and line art in dark colors on holographic backgrounds creates a premium, eye-catching result

Clear/Transparent Stickers

Clear stickers print on transparent vinyl, creating a "floating" effect when applied. They're elegant but require careful planning.

Design tips for clear stickers:

  • White areas in your design will be printed with white ink (opaque). Non-printed areas will be transparent
  • Consider the application surface—your design should work on both light and dark backgrounds
  • Light colors without a white underbase can look washed out or barely visible on dark surfaces
  • For maximum visibility, add a white ink underbase behind your colors
  • Clear stickers excel as window decals, product seals, and overlay designs

Paper Stickers

Paper stickers have a natural, tactile quality that vinyl can't replicate. They're ideal for:

  • Packaging labels and seals
  • Planner and journal stickers
  • Eco-conscious branding
  • Kraft-friendly, earthy aesthetics

Design tips for paper:

  • Colors print slightly softer and more natural on paper compared to vinyl
  • Warm tones and earthy palettes look particularly good
  • Paper is not waterproof—design accordingly (indoor use, packaging, journals)
  • Kraft paper specifically pairs well with cream, brown, green, and muted color palettes

Design Best Practices for Selling

Technical correctness is the foundation. But designing stickers that sell requires a different set of skills.

Simplicity Sells

At sticker sizes (typically 2-4 inches), less is more. The stickers that sell best tend to share common traits:

  • One clear focal point. A character, a word, a single image. Not a complex scene.
  • Bold, readable elements. If text is part of your design, it should be readable from arm's length.
  • Limited color palettes. 3-5 colors work better than 15. Cohesive palettes look more professional and intentional.
  • Strong silhouettes. Your sticker should be recognizable even from a distance or at a glance.

This doesn't mean simple designs only—it means purposeful designs. A highly detailed illustration can work brilliantly as a 4-inch sticker. But that same level of detail crammed into a 1.5-inch sticker will look muddy.

Contrast and Readability

Contrast is your best friend at small sizes. Dark elements on light backgrounds (and vice versa) ensure your design reads clearly. Low contrast designs that look artistic on a large screen can become indistinct blobs at sticker scale.

Test your contrast: Squint at your design on screen. Can you still tell what it is? If the answer is yes, your contrast is good. If everything blends together, increase the contrast between your key elements.

Testing Your Design at Actual Print Size

This is the single most valuable habit you can develop:

  1. Open your design file
  2. Zoom to 100% (actual pixels)
  3. Measure a 3-inch area on your screen with a ruler (or use a digital ruler tool)
  4. Look at your design at that physical size

Does the text read clearly? Are the details visible? Does the overall composition hold up? What looks great filling your 27-inch monitor might look very different at 3 inches.

Even better: Print your design on your home printer at actual size. It won't match POD quality, but it'll show you scale issues immediately.

Designing for Social Sharing

Your sticker doesn't just need to look good in person—it needs to look good in photos. Because that's how most people discover and decide to buy stickers: through Instagram posts, TikTok hauls, and unboxing stories.

Tips for photogenic stickers:

  • Bold colors and high contrast photograph better than subtle, muted designs
  • Simple shapes create clean, recognizable thumbnails
  • Designs with "personality" (expressive characters, witty text, clever concepts) get shared more
  • Consider how your sticker looks on common surfaces: laptops, water bottles, phone cases
  • A mix of sizes in your product range gives customers more to photograph and share

Tools and Software for Sticker Design

You don't need expensive software to create professional sticker files. Here's a breakdown by skill level and budget.

Procreate (iPad) — Best for Illustrators

If you draw by hand, Procreate is exceptional. The brush engine is powerful, the interface is intuitive, and the latest versions support CMYK canvases.

For sticker design:

  • Set your canvas to at least 300 DPI at your target print size
  • Use the highest resolution your iPad supports
  • Export as PNG with transparent background
  • Procreate files are raster-based, so resolution is critical—never scale up

Price: ~$17 SGD one-time purchase

Canva — Best for Beginners

Canva is accessible, template-driven, and surprisingly capable for sticker design. It's not ideal for complex illustrations, but for typography, simple graphics, and text-based stickers, it works great.

For sticker design:

  • Use custom dimensions set to your target size at 300 DPI
  • Download as PNG with transparent background (Pro feature)
  • Keep designs simple—Canva isn't built for print precision
  • Double-check your export resolution

Price: Free tier available, Pro from ~$17 SGD/month

Adobe Illustrator — Best for Professional Vector Work

The industry standard for vector design. If you're building a sticker business seriously, Illustrator is worth the investment.

For sticker design:

  • Work in CMYK color mode from the start
  • Use artboards set to your exact sticker dimensions plus bleed
  • Create cut paths as separate stroked paths
  • Export as SVG, PDF, or high-res PNG
  • Soft-proofing is built in and accurate

Price: From ~$38 SGD/month (Creative Cloud)

Figma — Best Free Collaborative Option

Figma is primarily a UI design tool, but it handles sticker design well—especially for text-based, geometric, and logo-style stickers. And it's free for personal use.

For sticker design:

  • Set frames to exact dimensions at 300 DPI equivalent
  • Export as PNG at 2x or 3x for sufficient resolution
  • Vector tools are solid for simple to moderate designs
  • Collaboration features make it easy to work with a partner or get feedback

Price: Free tier is generous; Pro from ~$20 SGD/month

Free Alternatives Worth Knowing

  • Inkscape — Open-source vector editor, similar to Illustrator. Great for SVG-based sticker designs.
  • GIMP — Open-source raster editor, similar to Photoshop. Handles PNG export well.
  • Photopea — Browser-based editor that works like Photoshop. No install needed, supports CMYK preview.

Common Design Mistakes (and How to Avoid Them)

These are the mistakes we see most often at The Potato Club. All of them are fixable. Most of them are preventable.

1. Too Much Detail at Small Sizes

The problem: Your design is beautiful at full screen size, but when printed as a 2-inch sticker, the details blur together and the design loses its impact.

The fix: Design at actual print size from the start. Set your canvas to the exact dimensions of your final sticker at 300 DPI. If details disappear at that size, simplify them. Bold shapes and clean lines always beat intricate details at sticker scale.

2. Low Resolution Images

The problem: Your file is 150 DPI or worse, 72 DPI (web resolution). The printed result is blurry, pixelated, or soft.

The fix: Always export at 300 DPI minimum. If your source file isn't high enough resolution, you need to recreate the design at the correct size—not upscale it. Upscaling adds pixels but not detail. It's the digital equivalent of zooming into a blurry photo and expecting it to become sharp.

3. Forgetting to Account for Bleed

The problem: Your design stops exactly at the cut line. Any minor cutting variation creates a visible white edge.

The fix: Extend your background color or design elements 3mm beyond the cut line on all sides. This is bleed—it gets trimmed off, but it ensures no white edges appear on your finished sticker.

4. Using RGB Neon Colors That Can't Print in CMYK

The problem: You designed with electric blue (#00FFFF), neon pink (#FF10F0), or other RGB colors outside the CMYK gamut. The printed result looks dull and different from your screen.

The fix: Design in CMYK mode when possible. If working in RGB, use the CMYK preview/soft-proof feature to check how colors will actually print. Avoid colors that shift dramatically during conversion—stick to colors that fall within the CMYK gamut.

5. Inconsistent Sizing Across a Collection

The problem: You designed ten stickers for a collection, but they're all slightly different scales. Some look huge, some look tiny, and they don't work well together as a set.

The fix: Before starting a collection, define your sizes. If your hero sticker is 3 inches, your supporting stickers might be 2 inches, and your accent stickers 1.5 inches. Design each within its defined size and check that they're proportionally consistent.

6. Tiny, Unreadable Text

The problem: Text smaller than 6pt (about 2mm tall) becomes illegible in print, especially on textured materials.

The fix: Minimum text size is 6pt for clean sans-serif fonts, 8pt for serif or script fonts. If your text is important enough to include, it's important enough to read.

7. Not Testing with a Sample

The problem: You launch your product listing based on how the design looks on screen. The first customer order reveals color or quality issues.

The fix: Always order a sample first. Always. At The Potato Club, a single die-cut sticker starts from $2.00 SGD. That's a two-dollar insurance policy against a bad first impression. Order one. Check it. Then launch with confidence.

How The Potato Club Handles Your Files

You might wonder what happens after you upload your file to us. Here's our process—because transparency builds trust, and we want you to know exactly what we do with your designs.

What We Check

  1. Resolution verification. We confirm your file meets our minimum 300 DPI requirement at the ordered size. If it doesn't, we'll reach out before printing.

  2. Color review. We check for obvious RGB-only colors that will shift significantly in print and flag potential issues.

  3. Bleed assessment. We verify that your design extends to the cut line with adequate bleed. If it's tight, we'll let you know.

  4. Cut path review. For die-cut stickers, we check that the cut path is clean and achievable. If your design has elements that might not cut cleanly, we'll suggest adjustments.

  5. Material compatibility. We make sure your design works well with your chosen material. If we think holographic or clear vinyl might not suit your design, we'll recommend alternatives.

What We Don't Change

We don't modify your design without your permission. We don't adjust colors, remove elements, or "fix" things on our own. Your design is your design. What we do is flag potential issues and give you the information to make informed decisions.

Our Quality Promise

Every sticker we ship has been printed, cut, and inspected by our team in Singapore. If something arrives damaged, misprinted, or significantly different from what your file should produce, we'll remake it. That's our commitment to you.

Getting Help with Your Files

Not sure if your file is ready? That's what we're here for. Send us your design before ordering and we'll give you honest feedback—no charge, no obligation. We'd rather help you get it right upfront than have you disappointed with the result.

Reach us at @thepotatoclub.store on Instagram or TikTok, or through our website at thepotatoclub.store.

What File Format Should I Use for Sticker Printing?

This is one of the most common questions we get, so let's answer it definitively:

For die-cut stickers with custom shapes: PNG with transparent background, 300 DPI, with 3mm bleed.

For simple shapes and logos: SVG with embedded cut path, or PDF with vector elements.

For sticker sheets with a full printed background: PNG or high-resolution PDF.

If you're not sure: PNG at 300 DPI with transparent background. It works for almost everything and is accepted by every POD platform.

Avoid: JPG for custom shapes (no transparency support), low-res screenshots, files copied from social media (72 DPI), and any file you found on Google Images.

Bringing It All Together

Designing for print on demand isn't complicated, but it does require attention to detail. The principles in this guide—resolution, color management, bleed, material awareness—aren't restrictions. They're tools. Once you internalize them, they become part of your creative process, not a checklist you dread.

The best sticker designers aren't necessarily the best artists. They're the ones who understand the medium. They know that a neon color that looks incredible on screen won't print the same way. They know that 3mm of bleed is the difference between a clean edge and a white sliver. They know that testing at actual size catches 90% of problems before they become complaints.

Start with the checklist. Order samples at thepotatoclub.store/collections/custom-prints. Learn what works with your style on each material. And don't skip the sample step—your future reviews will thank you.

Next up: In Part 5, we're tackling one of the most debated topics in POD: pricing. How do you price a $2 sticker so that you actually make money? What should you charge on Etsy vs. your own store? How do competitors price their products—and should you even care? It's all coming in the next installment.
