eBay: The Everything Marketplace
eBay remains the largest reselling platform with over 135 million active buyers worldwide. It's the only platform where you can sell literally anything — electronics, auto parts, collectibles, clothing, industrial equipment, vintage items. If you can name it, someone has sold it on eBay.
eBay's fees hover around 13.25% total (including payment processing through Managed Payments). The audience is massive but competitive. SEO-optimized titles and item specifics matter enormously for eBay visibility — which is why tools like RoastAFlip's eBay listing generator can significantly boost your sell-through rate.
Poshmark: The Fashion-First Platform
Poshmark dominates in women's fashion, designer brands, and shoes. Its social features — sharing listings, Posh Parties, following closets — create a community-driven selling experience. Items that get shared frequently sell faster. Active sellers who share their closets daily see significantly better results.
The downside is Poshmark's 20% commission, the highest of the three platforms. This means you need higher margins to stay profitable. Poshmark works best for items that command premium prices — designer brands, sought-after athletic wear, and trending fashion. Use RoastAFlip's free profit calculator to check your margins before listing.
Mercari: The Budget-Friendly Marketplace
Mercari has the lowest fees at roughly 10% plus payment processing, making it the most seller-friendly platform for margins. It works well for general merchandise — home goods, toys, games, casual clothing, and everyday items that might not command premium prices on Poshmark.
Mercari buyers tend to be price-sensitive and love deals. Smart pricing and good photos matter more here than on other platforms. The audience is smaller than eBay's but highly engaged. Mercari's simplicity also makes it the easiest platform for new resellers to start on.
The Best Strategy: Sell on All Three
The most successful resellers in 2026 don't pick one platform — they list everywhere. Each platform reaches a different audience. An item that sits for months on eBay might sell in a day on Mercari. A designer bag that gets no traction on Mercari could get into a Posh Party and sell at full price.
The challenge is creating listings for each platform. That's where RoastAFlip helps — take one photo and generate platform-specific listings for eBay, Poshmark, Mercari, and Facebook Marketplace. Each listing is tailored to that platform's format, search algorithm, and buyer expectations.

Which platform is best for clothing?
Poshmark is the best platform for women's fashion, designer brands, and trendy clothing. eBay is better for men's vintage clothing, sportswear, and niche brands. Mercari works well for everyday casual clothing at lower price points. Many resellers list clothing on all three for maximum exposure.
Where do items sell the fastest?
