Overpayment Shipping Refund Scam on Facebook Marketplace
A Facebook Marketplace buyer sends a payment for more than the agreed price, claiming it covers 'extra shipping,' then asks the seller to refund the difference before the original payment is discovered to be fake or reversible.
Part of: Overpayment / Shipping Refund Scam
Last reviewed: 5 July 2026
Most buyers on Facebook Marketplace are ordinary people, and genuine payment mistakes happen. This scam borrows that plausibility: a buyer arranging shipping sends more than the agreed price, by check, bank transfer, or a convincing payment screenshot, then apologetically asks for the difference back through a fast channel like Zelle, Cash App, or gift cards. The pressure to be a decent seller does the rest. The distinction that matters is the gap between a payment that appears cleared and one that is final; the original payment can still bounce or be reversed days after your instant, irreversible refund has gone.
How this scam works on Facebook Marketplace
A buyer messages interest in a Marketplace listing being shipped rather than picked up locally, then sends a payment — often a check, a fake payment confirmation screenshot, or a bank transfer — for an amount noticeably higher than the agreed price. The buyer explains this was accidental or covers 'extra shipping and handling,' and asks the seller to refund the difference via a separate, fast method like Zelle, Cash App, or gift cards. The seller, seeing what looks like a cleared or confirmed payment, sends the 'refund' promptly, only to discover days later that the original payment was fraudulent, forged, or reversed, leaving the seller out both the refunded amount and the item if it was already shipped. Because Marketplace transactions for shippable items are less protected than in-person cash sales, sellers who ship an item alongside issuing a refund can lose on both fronts at once.
Common red flags
- Buyer sends a payment for more than the agreed price and asks for the difference back
- Original payment is a check, money order, or screenshot rather than a fully cleared, verified transfer
- Buyer requests the refund via a fast, hard-to-reverse method like Zelle, Cash App, or gift cards
- Urgency to send the refund quickly, often citing a 'shipping deadline' or personal excuse
- Buyer is unusually flexible about the price and eager to move the transaction outside Marketplace's messaging
How to protect yourself
- Never refund an overpayment until the original payment has fully cleared and settled in your account, which can take days for checks
- If a buyer overpays, ask them to cancel and resend the correct amount rather than sending a refund yourself
- Be suspicious of any buyer who overpays and immediately requests money back through a different method
- Ship items only after full, confirmed, and cleared payment for the agreed amount
- Report suspicious buyers to Facebook Marketplace before engaging further
How to report it
- Report the buyer's profile and messages to Facebook Marketplace's fraud reporting tool
- Report a forged or bounced check to your bank and to local law enforcement
- File a complaint with the FTC at reportfraud.ftc.gov describing the overpayment scheme
- Report the receiving refund payment method (Zelle, Cash App) to that provider's fraud team
Frequently asked questions
How long does it actually take for a check or bank transfer to fully clear so I know it's safe?
This varies by payment method and your bank's specific policies, so check with your bank directly, but checks in particular can appear to clear within a day or two while still being reversed as fraudulent days or weeks later. Waiting for full, final clearance rather than an initial 'available balance' is the safer approach.
Can Facebook Marketplace help me get my money back if I already sent a refund to a scammer?
Facebook Marketplace doesn't process these payments directly, so it can't reverse a Zelle, Cash App, or gift card refund you sent — recovery depends on your bank or the payment provider. Report the buyer's profile to Facebook regardless, since this can help prevent the same scam from targeting other sellers.
Why do these buyers specifically target items being shipped rather than picked up locally?
Shippable listings create a natural reason to discuss payment and 'shipping cost adjustments' over messages without ever meeting in person, giving the scammer more room to claim an accidental overpayment. In-person, cash-only local sales remove most of this opening since payment and pickup happen together.
Why shouldn't I refund an overpayment right away?
Checks, money orders, and some transfers can take days to fully clear and can be reversed or found fraudulent after you've already sent a refund, leaving you out both the original item and the refund amount.
What should I do if a Marketplace buyer overpays me?
Ask them to cancel the original payment and resend the correct amount rather than sending any money back yourself, and don't ship the item until the correct payment has fully cleared.
