To celebrate the grand opening of gaming departments at MicroCenter stores, they are offering $100 mail-in-rebates on the Xbox 360 Core or Premium systems. This would bring the price of the Core down to $200 and the price of the Premium down to $300. It is likely to be in-store only and the offer begins today and is good through December 3 or when supplies run out. (If you do get this, I would very much recommend also getting Gears of War, it's the cat's pajamas, yo.) Thanks, Soheil
