eBay Seller Sent Wrong Item: Can You Keep It?

If an eBay seller sent the wrong item, can you keep it? Not as a free gift. Federal law lets you keep merchandise you never ordered, but a wrong item on an order you actually placed is a fulfillment error, not unsolicited merchandise. You’re entitled to the correct item or a full refund through eBay’s Money Back Guarantee, and sometimes the seller will tell you to keep the wrong item on top of that, but the choice isn’t yours to make unilaterally.

Why the “Free Gift” Rule Doesn’t Apply

The confusion traces back to a real federal law. If a company mails you something you never asked for, you can treat it as a gift with no obligation to pay or return it.¹ The statute exists to stop businesses from shipping random products and then demanding payment.

A wrong-item shipment on an eBay order is a different animal. You initiated the transaction. You agreed to buy something specific. The seller made a mistake fulfilling it. The FTC classifies this as a billing error: a charge for goods “not delivered as agreed.”² That’s a dispute over a purchase you made, not a windfall.

Keeping the wrong item quietly also carries some legal exposure. The seller still owns that product. Under common-law principles of unjust enrichment and conversion, holding onto someone else’s property when you know it was sent by mistake can create liability. A seller is unlikely to sue over a twenty-dollar mix-up, but the principle is real and the stakes rise with the item’s value.

When the Seller Tells You to Keep It

There’s one clean path to legitimately keeping the wrong item: the seller offers that outcome. eBay’s policy allows buyers and sellers to work out alternatives to a standard return and refund. A seller may offer a partial refund while you keep the wrong item, or ship a replacement without asking for the first one back.³ This happens most often with lower-value items, where return shipping would eat whatever the seller could recover.

If the seller writes back and says to keep it, you’re in the clear. Save the message in eBay’s system so there’s a record of the agreement.

What You’re Actually Entitled To

eBay’s Money Back Guarantee covers items that don’t match the listing, and that explicitly includes the seller sending the wrong item.³ A few points carry most of the weight:

No-returns policies don’t apply. Even if the listing says the seller doesn’t accept returns, you can still return a wrong item for a refund. The seller’s return policy governs buyer’s remorse, not fulfillment errors.³
The seller pays return shipping. For items that don’t match the listing, the seller covers the cost of getting the wrong item back.³
You have 30 days to report it. A return request must be opened within 30 calendar days of actual or estimated delivery, or within the seller’s stated returns window, whichever is longer.³

Missing the 30-day window is where buyers lose their leverage. Report the problem as soon as you notice it rather than waiting.

Step by Step: Handling a Wrong-Item Shipment

Order matters. Jumping straight to a formal case can sour a seller who would have fixed things quickly; waiting too long can cost you the refund entirely.

Verify the mistake. Compare what arrived to the listing you purchased. Take clear photos of the item, the shipping label, and any packing slip. This documentation is essential if the dispute escalates.
Message the seller through eBay. Use eBay’s messaging system so the conversation stays on the record. Describe the problem, attach the photos, and give the seller a reasonable window to respond. Many sellers will immediately offer a return label, a replacement, or a refund.
Open an “Item Not as Described” return. If the seller doesn’t respond within a couple of days or pushes back, open a formal return request through your purchase history and upload your photos.
Ship the wrong item back when instructed. Once the seller provides a prepaid return label, send it back promptly, with tracking, and keep the receipt. eBay looks for proof of return delivery when deciding the outcome.³
Ask eBay to step in if needed. If three business days pass without a return label or resolution, you can escalate.⁴

A practical note on refusing delivery: if you haven’t opened the package yet, you can mark it “Refused” and hand it back to the carrier for free return to the sender. Once you open the package, that option disappears. USPS policy is that opened mail cannot be refused and returned without the recipient paying new postage.⁵ Most buyers open the package before realizing anything is wrong, so the eBay return process is usually the better route.

When the Seller Won’t Cooperate

If the seller ignores your messages or refuses to resolve the problem, you can ask eBay to step in once three business days have passed since you opened a return request or reported an issue.⁴ Find the item in your purchase history, open the return details, and choose the option to escalate.

Don’t let a case go cold. eBay automatically closes a request that has had no activity for 21 business days.⁴ If the seller accepted the return but never sent a prepaid label, use eBay’s support chat rather than waiting for a button that may not appear.

Credit Card Chargeback as a Backup

If eBay’s resolution process fails, a credit card chargeback is your next line of defense. The Fair Credit Billing Act defines a billing error to include charges for goods “not delivered as agreed,” which covers a wrong item.⁶

Send a written dispute to your card issuer at the address designated for billing inquiries, not the payment address, within 60 days of the statement that first shows the charge. The issuer must acknowledge the dispute within 30 days and resolve it within two billing cycles, capped at 90 days.² You don’t have to pay the disputed amount while the investigation is open.

Debit cards are weaker ground. The consumer protections for debit transactions don’t match credit cards, and you may not recover a wrong-item payment through your bank’s dispute process.² That’s a reason to use a credit card for online purchases when you can.

The One Case Where You Can Actually Keep It: Brushing Scams

If a package shows up and you never ordered anything, the analysis flips. In a brushing scam, a seller ships cheap products to your address without any order from you, then uses your name to post fake verified-purchase reviews.⁷ Because you never ordered the item, it qualifies as unordered merchandise under federal law, and it’s yours to keep.

The real problem in a brushing situation is that someone has your personal information. If a package arrives that you didn’t order:

Change your passwords on online shopping accounts, especially any accounts that share a password.
Don’t contact the sender. Reaching out often invites social engineering attempts to pull more information from you.⁷
Monitor your credit reports at AnnualCreditReport.com for accounts opened in your name.
Report the scam to the FTC at ReportFraud.ftc.gov and to the marketplace where the seller operates.⁷

The line is clean. If you placed an order and got the wrong thing, that’s a fulfillment error and you work it through eBay. If a random package shows up that you never ordered at all, that’s unsolicited merchandise and it’s yours.
