TL;DR
Almost every reselling scam relies on one trick: getting you to act before the money is truly yours. Learn the common patterns - overpayment refunds, fake verification codes, prepaid shipping labels, and moving off-platform - so you can spot them in seconds and refuse without a second thought.
Scammers do not target sellers who are careful. They target sellers who are in a hurry, who want the sale badly, and who have not seen the trick before. The good news is that reselling scams recycle the same handful of scripts over and over. Once you know the patterns, they become almost funny in how obvious they are. This is the field guide to the ones you will actually run into.
The overpayment refund
A buyer sends more than the asking price - by accident, they say - then asks you to refund the difference. It feels like an easy favor. But the original payment reverses days later, so you are out both the item and the money you 'refunded'. The rule is simple: never refund an overpayment. Cancel the payment entirely, or wait until it has fully and permanently cleared before you do anything at all.
The fake verification code
The prepaid shipping label
For a shipped sale, a buyer offers to send their own prepaid label so you can ship right away. The label is often stolen or set to reroute the package to a different address, and it can be canceled after you have already handed the box to the carrier - leaving you with no item, no payment, and no tracking that helps you. Always buy and print your own label through the marketplace's checkout, so the tracking and protection are tied to the real sale.
The move off-platform
- A buyer wants to text or move to another app 'to make it easier' - which conveniently removes the marketplace's record and protection.
- A buyer sends a link to a 'secure payment page' that is really a fake site harvesting your login or card details.
- A buyer claims their payment app needs you to 'upgrade to business' first and sends money to cover it - money that never actually exists.
- A buyer pressures you to decide fast, because urgency stops you from checking. Slow down on purpose.
The one rule that beats them all
Every one of these scams needs you to give up the item or send money before the buyer's money is truly, permanently yours. So make that your single unbreakable rule: nothing leaves your hands until the payment is confirmed in your own account and cannot be reversed. You do not have to identify which specific scam it is. If a request asks you to act before you are actually paid, the answer is no.
Trust your gut, too. If a deal feels strangely eager, oddly complicated, or weirdly urgent, that discomfort is information. Walk away from a suspicious buyer and the next honest one will be along shortly. Losing a sale costs you a little time; falling for a scam can cost you the item and real money.
Common questions
What is the single rule that stops most scams?
Nothing leaves your hands - not the item, not a refund - until the buyer's payment is confirmed in your own account and cannot be reversed. Every reselling scam relies on getting you to act before the money is truly yours, so refusing to do that shuts nearly all of them down.
How does the overpayment scam work?
A buyer sends more than the asking price, claims it was a mistake, and asks you to refund the difference. The original payment later reverses, so you lose both the item and the refund. Never refund an overpayment - cancel it, or wait until it has fully and permanently cleared.
Why should I never read back a code a buyer sends me?
Because that code is almost always a two-factor login code for your own account. A scammer posing as a buyer uses it to take over your account or a payment app. No real payment ever requires you to read a code aloud, so never share one with anyone.
Are buyer-provided prepaid shipping labels safe?
No. A prepaid label from a buyer may be stolen, set to reroute the package, or canceled after you drop it off - leaving you with no item and no payment. Always buy and print your own label through the marketplace checkout so tracking and protection are tied to the real sale.
Why do scammers want to move off the platform?
Moving to text or another app removes the marketplace's record and protection, and any link they send may be a fake payment page harvesting your details. Keep the conversation and the payment inside the platform where you are covered.
What should I do if a deal just feels off?
Walk away. If a buyer seems strangely eager, oddly complicated, or weirdly urgent, that discomfort is useful information. Losing one sale costs a little time; falling for a scam can cost you the item and real money. The next honest buyer will be along shortly.
