This deal has ended.
Overstock just got in a few varieties of XBox 360 packages. The best is on the XBox 360 Core Bundle (an XBox console without Hard Drive, a wireless controller, Ghost Recon Advance Warfighter and Burnout Revenge). It is only $435 after a $25 off $350 coupon. If you have issues with the coupon it may be because orders comprised solely of "media" are excluded and media usually includes anything video game. In that case, you must also buy a non-media item. Look here, here and here for cheap ideas.
