Just a friendly tip from your friends at G4tv.com: on Saturday, November 8th at Wal-Mart the following deal is available at 8AM:
Purchase a $399 80GB PlayStation 3 and receive a $100 gift-card FREE.
The ad notes that this is only "while supplies last", but each store will receive a minimum of 4 PS3's to sell. We recommend getting there early if you want to get this deal.
They are also selling the $129 PlayStation 2 with a $30 gift card if you still need one of those (again, minimum of 4).
Thanks to Joystiq for finding the ad.
