I know Sam's club, which is a Costco look-a-like gets some games out on time. I think they get most of the big games. But that may also be because they are associated with Wal-Mart.
As for pre-orders? I just recently got on the pre-order band wagon. I pre-odered Metroid Prime 3 and Guitar Hero 3 for the Wii from GameStop/EB. I can let you know how it goes after August 28th. They better have me a copy. I'm sure they will.
