Scott PolinThe same type thing is going on between Yahoo and Ebay. There was a PSA 5 1953 Mantle for sale on Yahoo at buy it now for $1083, the person who eventually bought it listed the same scan and item on Ebay at the same time. When the bidding on Ebay exceeded $1083 the seller on Ebay bought the Yahoo item.
