This maybe should be in GAC's thread, but I thought it was good enough a deal to post on its own:
Glory of Heracles - $10.99-$10 credit = $0.99 and qualifies for free shipping on orders over $25.
Great deal on a first-party title. I just picked this one up since I needed to order something else to bump it up to $25 for free shipping. Can't beat a new game for a buck, and I'll use that $10 credit sooner or later. Unrelated except that I did all this at about the same time, but in case anyone cares, I also bit on Super Mario Galaxy 2 at GameStop.com for 39.99 - 20 in credit with free shipping (use codes GS20 and SAVER). The codes didn't seem to stack, but just keep going and they'll both apply before you pay.
