Reseller Pro Tips
Check eBay Sold Listings First
Before buying anything at a bin store, search the item on eBay and filter by "Sold" to see actual selling prices. This tells you exactly what buyers are paying, not just what sellers are asking.
Factor in Your Time
Listing, photographing, packaging, and shipping each item takes 15-30 minutes. Make sure your profit per item justifies the time. Most experienced resellers set a minimum profit threshold of $10-15 per item.
Sell Locally to Maximize Margins
Facebook Marketplace charges 0% fees for local pickup sales. For large, heavy, or fragile items, selling locally eliminates both platform fees and shipping costs, dramatically increasing your profit.
Use the 3x Rule
A common rule among resellers: only buy an item if you can sell it for at least 3 times what you paid. At bin store prices ($1-10 per item), this is surprisingly achievable for electronics, tools, and brand-name goods.
Frequently Asked Questions
How much can you make reselling bin store items?
Most experienced resellers report making $200-$800 per week from bin store finds. Your profit depends on how well you pick items, the platforms you sell on, and how fast you list. Electronics and brand-name items typically offer the highest ROI.
What platform fees should I expect?
eBay charges about 12.9% plus $0.30 per order. Facebook Marketplace is free for local pickup or 6% for shipped items. Poshmark takes a flat 20%. Mercari charges 10%. Amazon takes around 15% depending on the category. Always factor fees into your profit calculation.
Is reselling bin store items legal?
Yes. Once you purchase an item, the first-sale doctrine gives you the legal right to resell it. This applies to bin store items, thrift store finds, and any other legally purchased goods. You do not need permission from the original manufacturer.
How do I account for shipping costs?
Weigh your item after packaging and check rates on your platform. USPS Priority Mail flat-rate boxes are popular for medium items. For large or heavy items, sell locally on Facebook Marketplace to avoid shipping entirely. Our calculator lets you include shipping costs in the profit calculation.
What is a good profit margin for reselling?
Aim for at least 50% profit margin after all fees and shipping. Many bin store resellers achieve 200-500% ROI because purchase prices are so low. If an item does not have at least a 3x markup potential, most experienced resellers skip it.
Should I sell on eBay or Facebook Marketplace?
Use both. eBay is better for electronics, collectibles, and brand-name items because buyers search by specific product. Facebook Marketplace is better for large, heavy, or local-pickup items where you can avoid shipping fees entirely.
