[quote name='25MVPKing']just got in on this and picked up NHL '11. It wouldn't give me 2 at the price, and when I checked out I started a new order with Madden. By the time I did that one, the code said expired.

offtopic- brand new to CAG, who's a solid retailer for USED games?[/QUOTE]
Amazon Warehouse Deals are the best place for used games I've ever experienced. This is coming from someone who always prefers buying new, as I hate my games having scratches, etc. But sometimes, some games are rare and impossible to find new, so I shop here.
They seem to only sell used games in "Like New" condition and complete (game, manual, case, cover art). Not only that, I've yet to order a game that actually had any scratches (and I thoroughly check under a light). Also, if you ever have any issues, you have Amazon's stellar customer service.
Just check out the Amazon Warehouse thread here on this board, and see what you think.
