Best Items to Buy and Resell for Profit

Buying items at a low price and reselling them for a profit is one of the most accessible side hustles you can start today. No storefront, no inventory investment beyond what you're comfortable with, and no special credentials required. But the difference between resellers who make real money and those who waste time comes down to one thing: knowing what to buy.

After years of reselling on eBay and analyzing thousands of transactions, I've compiled this list of 18 item categories that consistently deliver strong profit margins. These aren't theory — they're based on actual sold data you can verify yourself using our free eBay price checker.

High-Margin Categories (50%+ Profit Potential)

These categories offer the biggest spreads between what you pay and what items sell for. They require more knowledge to source well, but the payoff is worth it.

1. Vintage Video Games & Consoles

Average profit margin: 60–200%

Retro gaming is booming. Complete-in-box games for systems like the Nintendo 64, GameCube, and original PlayStation regularly sell for multiples of what you'll pay at garage sales or thrift stores. A copy of Super Smash Bros. Melee found for $5 can sell for $40-60. Even loose cartridges for the Game Boy and SNES hold steady value.

Where to source: Garage sales, estate sales, Facebook Marketplace lots, and thrift stores. Look for boxes of "old games" that sellers don't want to sort through.

2. Vintage Clothing & Band Tees

Average profit margin: 100–500%

A faded Nirvana tee from 1992 can be worth $200+. Vintage single-stitch band shirts, 90s sportswear (Starter jackets, Champion reverse weave), and rare graphic tees from the 80s and 90s have an enormous collector market. The key is learning to identify genuine vintage from reprints — check the tag style, print quality, and fabric weight.

Where to source: Thrift stores (especially in smaller towns), estate sales, and vintage clothing lots on Facebook Marketplace.

3. LEGO Sets

Average profit margin: 50–150%

Retired LEGO sets appreciate like investments. A Star Wars UCS set that retailed for $200 can sell for $400-600 after it's discontinued. Even incomplete sets have value — individual minifigures from rare sets sell for $10-50 each. New, sealed sets are ideal, but used complete sets with instructions also sell well.

Where to source: Garage sales, estate sales (especially from families with older kids), and clearance sections at retail stores before sets retire.

4. Power Tools

Average profit margin: 50–100%

Name-brand power tools hold their value remarkably well. A used DeWalt drill set bought for $30 at a garage sale can resell for $60-80. Milwaukee, Makita, and Festool command premium prices even when used. Cordless tools with working batteries are the sweet spot — batteries alone can be worth $30-50.

Where to source: Estate sales, pawn shops, Facebook Marketplace, and garage sales in suburban neighborhoods.

5. Camera Equipment

Average profit margin: 40–80%

High-end camera lenses hold value for decades. A Canon L-series lens bought at an estate sale for $200 can resell for $400+. Vintage film cameras have also surged — the analog photography revival means cameras like the Canon AE-1 or Pentax K1000 sell for $100-200. Even camera bags and tripods from premium brands like Manfrotto flip well.

Where to source: Estate sales, camera shop trade-ins, Craigslist, and photography community buy/sell groups.

Reliable Mid-Range Categories (30–60% Margins)

These categories won't make you rich on any single item, but they're consistent and easy to source in volume. Great for building steady income.

6. Athletic Shoes & Sneakers

Average profit margin: 30–80%

The sneaker resale market is massive and mature. Limited releases from Nike, Jordan, and Adidas Yeezy can flip for double retail on release day. But you don't need to chase hype drops — even general-release Nike Dunks bought on clearance for $60 can resell for $80-100 in popular sizes. Used premium sneakers in good condition also sell well.

Where to source: Outlet stores, clearance sales, Nike SNKRS app (for limited releases), and thrift stores for vintage finds.

7. Small Kitchen Appliances

Average profit margin: 40–70%

KitchenAid stand mixers are the gold standard — a used one bought for $50 can sell for $120-180 depending on the model and color. Vitamix blenders, Breville espresso machines, and Instant Pots in good condition all flip reliably. These items are heavy, which deters casual sellers and keeps margins healthy for those willing to ship them.

Where to source: Thrift stores, estate sales, wedding registry returns at outlet stores, and Facebook Marketplace.

8. Textbooks & Specialized Books

Average profit margin: 50–200%

Skip the common novels — they're worth pennies. Focus on college textbooks (especially STEM and medical), technical manuals, out-of-print reference books, and niche hobby guides. A nursing textbook found for $2 at a thrift store can sell for $30-60 on eBay. Scan ISBNs with your phone to check values before buying.

Where to source: Library sales, thrift stores, college dorm move-out dumpsters, and estate sales.

9. Board Games & Puzzles

Average profit margin: 50–150%

Out-of-print board games are a sleeper category. Games like HeroQuest, Fireball Island, and Dark Tower sell for $100-300+. Even modern designer board games (Gloomhaven, Wingspan limited editions) flip well. Complete sets with all pieces are key — always check before buying.

Where to source: Thrift stores, garage sales, estate sales, and clearance sections at Target and Barnes & Noble.

10. Watches

Average profit margin: 30–100%

You don't need to deal in Rolex to make money flipping watches. Mid-range brands like Seiko, Citizen, and Casio G-Shock have dedicated collector bases. A vintage Seiko diver found for $20 at a flea market can sell for $80-150. Learn to identify movements and you'll spot deals others miss.

Where to source: Estate sales, pawn shops, flea markets, and auction lots.

11. Cast Iron Cookware

Average profit margin: 40–100%

Vintage cast iron (Lodge, Griswold, Wagner) has a passionate collector market. A Griswold #8 skillet found for $10 at a garage sale can sell for $50-100+. Even modern Lodge pieces bought at thrift stores for $5-8 resell for $20-30. Cast iron is virtually indestructible, so even rusty pieces can be restored and sold.

Where to source: Estate sales, garage sales, thrift stores, and antique malls.

Volume Categories (Consistent, Lower Margins)

These won't deliver huge per-item profits, but they're easy to source in bulk and sell quickly. Good for building cash flow and learning the reselling process.

12. Clothing (Specific Brands)

Average profit margin: 30–60%

Focus on brands that hold value: Patagonia, North Face, Lululemon, and premium denim (AG, 7 For All Mankind, True Religion). A Patagonia fleece bought for $8 at Goodwill can sell for $30-50. The key is being selective — only buy brands you know sell, in good condition, without stains or damage.

13. Media (DVDs, Blu-rays, CDs)

Average profit margin: 30–80%

Most DVDs are worthless, but specific titles sell for $15-50+: out-of-print films, complete TV series box sets, criterion collection discs, and niche genres (anime, horror, workout videos). Blu-ray 4K steelbooks are particularly profitable. Buy these for $1-2 at thrift stores and garage sales.

14. Sports Equipment

Average profit margin: 30–50%

Golf clubs (especially premium brands like Titleist, Callaway, and TaylorMade) are a reliable flip. A set of irons bought for $30 can sell for $80-150. Tennis rackets from Wilson and Head, baseball gloves from Rawlings, and ski equipment also flip well. Seasonal timing matters — list golf clubs in spring, ski gear in fall.

15. Printer Ink & Toner Cartridges

Average profit margin: 40–70%

Sealed, unexpired printer cartridges are a hidden gem. People upgrade printers and have unused cartridges sitting around. You'll find them at estate sales and garage sales for $2-5, and they sell for $15-30 on eBay. HP, Canon, and Brother cartridges move the fastest.

16. Vacuum Cleaners

Average profit margin: 40–60%

Dyson vacuums are the winner here. A used Dyson V8 bought for $40 can sell for $80-120 after a thorough cleaning. Shark and Miele also hold value. Most people selling vacuums at garage sales are upgrading — their "old" vacuum often has years of life left.

17. Musical Instruments

Average profit margin: 30–60%

Guitars, keyboards, and band instruments hold value well. A Yamaha keyboard found for $20 at a garage sale can sell for $60-80. Vintage guitars are a specialty niche where experienced flippers make serious money. Even guitar pedals and accessories have strong resale markets.

18. Vintage Pyrex & Glassware

Average profit margin: 50–200%

The Pyrex collector community is thriving. Rare patterns like Butterprint, Gooseberry, and Lucky in Love command premium prices. A Pyrex mixing bowl set bought for $5 at a garage sale can sell for $30-80 depending on the pattern and condition. Corning Ware, Fire-King, and Anchor Hocking pieces also have strong markets.

How to Evaluate Any Item Before Buying

Regardless of category, follow this quick process before buying anything to resell:

1. Check the sold price — Open ItemsToFlip and search for the exact item. Look at what it actually sold for, not what people are asking.
2. Factor in all costs — Our tool automatically calculates eBay fees (12.9% + $0.30) and shipping estimates, so you see your real profit.
3. Check sell-through rate — An item might sell for $50, but if only 2 out of 100 listings sold, it could sit in your inventory for months.
4. Assess condition honestly — Flaws you overlook will come back as returns. Factor any defects into your pricing.
5. Consider shipping logistics — Fragile items (glass, ceramics) and heavy items (cast iron, tools) cost more to ship and have higher breakage risk.

Where to Find Items to Buy and Resell

The best sourcing spots depend on what you're selling, but these consistently produce finds across all categories:

• Thrift stores — Goodwill, Salvation Army, and local thrift shops are the backbone of reselling. Visit regularly since inventory turns over constantly. See our thrift store sourcing guide for category-by-category tips.
• Garage and estate sales — The best margins in reselling. Sellers want items gone and will negotiate. Check our garage sale flipping guide for route planning and negotiation strategies.
• Facebook Marketplace — Great for buying lots (bulk groups of items) at a discount. Search "moving sale" or "everything must go" for motivated sellers.
• Retail clearance — Target, Walmart, and Amazon clearance sections occasionally have items below resale value. Works best with toys, LEGO, and seasonal items.
• Auctions — Online and in-person auctions can yield large lots at below-market prices. Storage unit auctions are high-risk but occasionally very rewarding.

Getting Started: Your First Week

If you're new to reselling, here's a practical first-week plan:

1. Pick 2-3 categories from this list that interest you. Specializing helps you learn faster.
2. Set a budget — Start with $50-100 for inventory. This limits risk while you learn.
3. Source locally — Hit 3-4 thrift stores and check Facebook Marketplace daily.
4. Check every item — Use ItemsToFlip to verify prices before buying. This habit alone will prevent most costly mistakes.
5. List immediately — Don't hoard inventory. List items within 48 hours of buying them.
