$299 clearance-sale 20GB Xbox 360 ... or the new $349 60GB 360 for that matter. Dell.com has the $450 Xbox 360 Elite for the low, low price of $299. But that's not all! If you act now (or, presumably, at any point between now and when they inevitably sell out) you'll also get copies of Marvel: Ultimate Alliance and Forza 2, along with two rather unseemly faceplates.
Update: The promotion has ended -- it's back to $450.
