What should I sell on?
Pick the item type, price range, shipping situation, and selling style. The quiz ranks the marketplaces most likely to fit first, then sends you into fee calculators and item-specific guides with the decision narrowed down.
Direct answer: eBay is the safest first check for broad searchable items, Poshmark and Depop fit fashion, Etsy fits handmade or vintage, Facebook Marketplace fits bulky local pickup, StockX and Whatnot fit specialist collector audiences, and Amazon fits catalog-style inventory.
Facebook Marketplace
Best when local pickup avoids heavy shipping, fragile packaging, or buyer return friction.
Local demand and buyer reliability matter more than fee math for pickup transactions.
Depop
Best for trend-led fashion, vintage clothing, streetwear styling, and younger buyer intent.
Great styling can beat fee math, but weak photos or generic inventory may underperform.
Hold sale price, shipping, and item cost constant before choosing. A smaller platform with stronger buyers can beat a cheaper fee model.
Check the quiz result against fee data
The quiz ranks marketplace fit by item type, shipping situation, price band, and selling style. Use the Fee Index for same-input marketplace fee rows, Fee Changes for recent policy updates, and Seller Reports for dated summaries of which platforms are getting more expensive for resellers.
If two marketplace recommendations are close, use the data assets as the evidence layer before running your exact listing through a calculator.
Use the quiz as a first pass
The best platform is rarely only the lowest fee. A marketplace can charge more and still win if its buyers search for the item, trust the category, or pay enough of a price premium to offset the fee gap.
Once the quiz narrows the field, rerun the actual sale price, shipping cost, and item cost in the calculator. That keeps audience fit and fee math in the same decision instead of treating either one as a guess.
Next checks
If two platforms score close together, compare both with the same inputs. If one platform clearly wins on audience fit, check whether its fee model still leaves enough margin after shipping and cost of goods.
