With Black Friday (The day after Thanksgiving) sales still a good three weeks away, Wal-Mart will be having some in-store specials to jump start Christmas shopping this holiday season. The fun starts this Saturday at Wal-Mart stores at 8AM. Buy a 80GB PS3 at regular price and get $100 Wal-Mart gift card. You can use that $100 towards the sale on Greatest Hits games which are usually $30 but will be $20. Also, if you buy either a PSP or a PS2 at regular price you will get a $30 gift card.
