Toys r us, circuit city or FYE. I voted FYE only because every FYE near me carries no games. CC and TRU suffer from the same "OMG its on sale at a really good price, lets make sure we sell all of our stock and we'll never get any more in stock again".
I'm thinking of those 2 deals that are currently listed as best b&m deals of the year. CC did buy 1 get 1 free for xbox live accessories, which meant points cards were covered. Good luck finding any, every !&@!&#)!& store was sold out.
TRU... I wanted Orange box and not 1 !@(&# store had it in stock during the week of that buy 2 get 1 free deal. Following week, they had titles galore.
