I have a lot of doubles of 2008 Upper Deck Series 1 & 2 and 2008 Upper Deck Heroes. If you are looking for something specific just drop me an email or comment here and let me know, I can find it for you and we can work something out.
But damn, I can't go through all those 2008 UD cards and post my doubles it'll take too much time. Plus this could be a way to get to know more bloggers/collectors out there.
I'm a programmer who is originally from New Jersey transplanted to North Carolina. I'm a big Yankee fan and just an all around fan of the game. I collect Don Mattingly cards specifically but on occasion I build sets or buy older cards. I've just started collecting again (July 2008) after an almost 12 year hiatus.
