The seller I get emailed the most about from eBay is ulrealdealz00, and they are back selling autographs on eBay again. I know at least one card was returned to this seller as counterfeit, and they keep selling the same cards over and over again, and they are either using the same scans for some of their auctions or they are selling the same card over and over again. . .
Use caution when dealing with any seller you aren’t familiar with. . . Ask questions. . . does the image in the auction show the card you are buying, do they guarantee the card is genuine, what is their return policy.
Never buy a card without seeing a scan or photo of the card you are buying, and if the seller won’t guarantee the card is authentic, or if they don’t accept returns — run!
Good luck!
