The question isn’t which resale platform is “best” — it’s which one matches the inventory you already have and the amount of time you can spend running it. Trying to manage listings across five apps before your first sale is the fastest way to get overwhelmed and quit before you’ve learned anything.
eBay charges roughly 13.25% plus $0.30 per sale and reaches a massive, global, search-driven audience. It’s the strongest fit for hard goods, vintage items, electronics, collectibles, and designer apparel — anything a buyer is likely to search for by specific name or model rather than browse for.
Poshmark runs a flat 20% fee (or $2.95 on anything under $15) in exchange for a genuinely social marketplace — buyers there like sharing, offering, and bundling. It’s a strong fit for mid-to-high-end clothing, shoes, handbags, and beauty products, especially if you’re willing to engage with the community side of it.
Mercari keeps payment processing fees low, around 2.9% plus $0.50, and attracts bargain hunters who want a fast, casual, phone-first buying experience. Everyday apparel, toys, small electronics, decor, and trend items all move well there.
Etsy charges a 6.5% transaction fee plus a small listing and processing fee, and its audience is specifically looking for curated, handmade, or genuinely vintage items — 20 years or older, by Etsy’s own definition. True vintage home decor, antique clothing, and handmade craft supplies fit this audience best; everyday secondhand basics generally don’t.
Whatnot takes an 8% commission plus standard processing fees and runs on live video auctions with a highly engaged, fast-moving crowd. Trading cards, estate sale finds, vintage apparel, and bulk inventory tend to do especially well in that live-auction format.
Vinted charges sellers nothing — the buyer covers the fee — which makes it a strong option for everyday secondhand apparel, shoes, and kids’ clothing sold to budget-conscious, person-to-person buyers.
The practical advice for a first platform: pick the one that matches what’s already sitting in your closet or storage bins, get comfortable with its shipping and listing flow, and only add a second platform once the first one stops feeling like a chore. A full side-by-side fee and audience comparison, plus a cross-listing workflow for once you’re ready to expand, is part of the Second Hand Muse Starter Kit.
