I always wondered about those, I've seen a couple similar deals here in Canada also either offering a 360 or a PS3.
Dell had (or still is) offering a free 360 with purchase of PC
Bell/Telus was offering a free 360 with 1 year contract
My boss purchased a 42 inch tv and got a free Elite (he gave Pro to his nephew for xmas)
Why do I only remember the 360 deals?? I really don't know??
