Guys i need some info on this auto card. I am thinking about buying a 2007 UD Kevin Durant auto patch black but i dont understand why is it only $249US "Buy it now" when the seller is saying that it would sell for $750US in his auction??? Some of these UD auto Black's are numbered #??/15 or #??/50 so what is the difference in the card with the numbering? Can someone help. Katrina
