In my city (in Canada) the best stores to buy games are:

Best

1. Zellers-They give you an exchange for another type of game or a refund.

2. EB & Compucentre (tied)-You can exchange 1X only for another type of game.


Worst

1. Walmart & Future Shop (tied)-Exchange for same game only.




I think this thread can apply to a lot of people because most stores are chain stores.
