How to Shop Secondhand Online Without Getting Scammed

Secondhand shopping stopped being a niche habit years ago, but the apps that make it easy, Depop, Poshmark, Vestiaire Collective, eBay, are also where scams live. The good news: the red flags are consistent across platforms, and the protections, when you actually use them, work.

Keep the money and the messages on the platform

This is the single biggest rule. Resale apps only protect you while the transaction stays inside their system. Depop's policy, outlined in Wirecutter's guide to buying and selling secondhand without getting scammed, gives buyers a window to flag a problem: if the item never arrives, or arrives different from the listing, or shows up damaged, you can open a claim and the platform steps in. The moment a seller asks to move the conversation to text, email, or a direct bank transfer "to avoid fees," that protection disappears. Depop's own COO has said as much: any seller who offers you a cheaper or faster deal outside the app is very likely scamming you.

Watch for the specific red flags that actually show up

Strange requests, a refusal to answer basic sizing or condition questions, insistence on communicating outside the app, requests for a "deposit" to hold an item, or payment via gift card or money order instead of a card. Those are the patterns that come up again and again in scam reports. On the buyer side, check the seller's profile before you commit: a complete profile with a real photo and a visible transaction history is a decent signal. Mixed reviews with comments like "item didn't match the photos" are a reason to walk away even if the price looks good.

Authenticating designer pieces before you pay

Who What Wear's breakdown of where to buy secondhand clothes online points to Vestiaire Collective as one of the more reliable options for designer resale specifically because of its authentication layer and its filtering tools, which let you set a size, color, and price range and get notified when a matching piece is listed. For higher-priced items, eBay's Authenticity Guarantee program adds a third-party check before the item ships to you. Platforms like The RealReal build authentication into every listing rather than leaving it to individual sellers. If you're buying something expensive on a site that doesn't authenticate automatically, ask directly for a certificate of authenticity, serial numbers, and close-up photos of the hardware, stitching, and interior tags before you send any money.

If you'd rather skip the peer-to-peer part of this altogether: ThredUp buys, inspects, and resells each item itself, so you're never negotiating directly with a stranger and there's no "move the conversation off-platform" request to watch for. It trades some of the vintage-hunt thrill for a lot less risk.

What a legitimate seller actually does

A seller with nothing to hide will send extra photos without hesitation, including shots with something like a dated note next to the item to prove the photo is current rather than recycled from an old listing. They'll answer questions about measurements, since vintage sizing rarely matches a modern size chart. They'll have policies clearly stated on returns, shipping, and bundling. None of that is a hard ask. If a seller gets defensive, vague, or pushy about closing the deal fast, that pressure is itself the warning sign, scammers rely on urgency so you skip the checks you'd normally do.

If something does go wrong

Report the user to the platform immediately rather than trying to resolve it privately. Most resale apps have a dedicated reporting flow, and timing matters: Depop, for instance, generally expects a seller to ship within a set window after payment clears, and gives buyers roughly a month after that to raise a complaint if the item never shows up or isn't what was described. If you paid by credit card, you also have a chargeback option through your card issuer, which is one more reason card payments beat bank transfers for anything bought secondhand.

The bottom line

Buying secondhand online is safe in the overwhelming majority of cases, and it's one of the more sustainable ways to build a wardrobe. The risk isn't the format, it's skipping the basic checks: stay on-platform, read the profile and reviews, ask for proof before you pay, and don't let anyone rush you past a red flag.
