Yes, Mercari is a legitimate app and marketplace for selling that is often compared to eBay. The selling process is easy—once listed, your item is available to ship nationwide, offering you a larger pool of potential buyers than if you had listed it locally on Craigslist.

What to Sell

You’d be amazed at what you can sell online. One person’s throw-away item really is another’s treasure. In fact, on Mercari, items in fair or poor condition generally sell faster than brand-new items. And it only takes about three minutes, on average, for Mercari users to create a listing. So jump in!

When to Sell

In-season merchandise always does best: avoid selling swimwear in January. Seasonal shopping surges—like Black Friday or back-to-school—are great times to sell. But for sellers of second-hand items, the periods following those big peaks can be just as fruitful—think of them as retail binge hangovers.

Where to Sell

Different marketplaces work for different items based on their size, value or scarcity. Do you think you can find a local buyer, or do you want to reach a nationwide audience? Are you OK meeting a stranger to exchange the item for payment? On Mercari, everything ships anywhere in the U.S., and there are no meetups.
