Beware of scam targeting people selling items online KTRK HOUSTON, Texas (KTRK) -- If you are looking to make extra money selling things online, be careful. You could lose the item and your money too. The Better Business Bureau is warning about a scam that targets people online, no matter what they are selling. Experts say it can happen to anyone. Victims of the scam list an item for sale online, and a buyer agrees to the price. Then, that buyer sends the seller more than the asking price of the item. The buyer then contacts the seller about the overpayment, asking them to refund that portion of the money.
