eBay vs Mercari vs Poshmark: which to sell on

These three come up together constantly, but they're not really rivals for the same sale — each one is strongest for a different kind of item. Pick by what you have, not by which app you already have installed. Here's how they actually differ, and a quick rule for each common category.

The one-line version

eBay is the generalist with the deepest buyer pool and the best pricing data. Mercari is the fast, low-friction app for everyday secondhand goods. Poshmark is the fashion marketplace, social and share-driven, built for clothing and accessories. If you remember nothing else: niche or electronic → eBay, ordinary stuff → Mercari, branded clothing → Poshmark.

eBay: reach and research

eBay's edge is the sheer size and specificity of its audience. Collectors, parts buyers, and bargain hunters for almost any category are already there, and its archive of completed sales is the best free pricing signal on the open web — the reason it anchors our sold vs. asking price guide. Auctions can also surface true market value for rare items when you don't know what to charge. The costs: listings take more effort to set up, and it's shipping-first, so it's overkill for a $10 t-shirt or a couch you'd rather sell locally.

Best for: electronics, collectibles, trading cards, parts and accessories, tools, media, and anything niche or hard to value.

Mercari: speed and simplicity

Mercari is the least fussy of the three. Snap a few photos, set a price, ship in a prepaid mailer. The audience is broad and general rather than specialized, which makes it a great default for everyday goods that don't have an obvious home — small electronics, kitchen and home items, toys, hobby gear, casual clothing that isn't a name brand. It has price suggestions, but those are guidance, not real sold comps, so still do your own homework. It's less ideal for high-end designer fashion (Poshmark's buyers care more) or deep collectibles (eBay's reach wins).

Best for: general secondhand household goods, small electronics, toys, and everyday clothing.

Poshmark: fashion and community

Poshmark is built around clothing, shoes, and accessories, with a social feed where sharing and "posh parties" drive visibility. If you're selling branded fashion — contemporary and mainstream labels especially — this is where the buyers who recognize and want those brands congregate. Shipping is a simple prepaid label the buyer pays for. It's a poor fit for electronics, furniture, or anything that isn't apparel or accessories, and the share-to-sell rhythm rewards sellers who stay active. For vintage and streetwear specifically, Depop is worth a look alongside it (covered in our best reselling apps roundup).

Best for: branded clothing, shoes, handbags, and accessories.

A rule of thumb by item

All three are free to list and take a fee when the item sells, plus payment processing; the exact structures differ and change often, so check each app's current fee schedule before you price. Cross-posting the same item to two of them and taking the first solid offer is a common, sensible move.

Whichever you pick, price it first

The app decides who sees your item; it doesn't decide what it's worth. Before you list on any of the three, identify exactly what you have and find what it has actually sold for recently — then price to the median, not the luckiest sale. That process is spelled out in how to find out what your stuff is worth, and if you'd rather skip the manual searching, Price×Point returns a real number from a photo — sold comps, asking, and retail in separate lanes — so you walk into any of these marketplaces knowing your price. You can also browse what specific used items sell for for real, dated sales.
