Has anyone heard of this scam or has been a victim?
After 3 weeks a Buyer sends a personal check to pay for an item that is twice the amount of the invoice. So happy that you finally got paid, you send the item and a refund of the extra cost. The buyer then puts a stop payment on the original check. So you would be out the item, the money & the amount you refunded.
Only part of this has happened to me. I am sending the original check back with a note.
