Gamestop
Every Best Buy near me has the worst god awful customer service, no game selection, and well crowds as bad as gamestop. I bought a lot of games from gamestop, particularly Japanese games. I am building up a Japanese gaming backlog for DS/PS3 so when those games go out of print, I will be able to play them. Gamestop has a lot of them for reasonable, I can see the case/manual and game disc before I buy, and the customer service is generally decent.
