Amazon's Video Game Deal of the Day kind of comes with other deals built-in. The retailer is bundling a $75 credit with sales of the 250GB Xbox 360 hardware bundle, which is priced at $300. So, by buying this, you instantly get at least one free game to go with it.
Unless, of course, you choose to use that credit in other ways -- that's up to you. Maybe you want to buy a bunch of Microsoft Points. That works! Or maybe you want to wait on the whole Xbox 360 game thing for a while, just watch Netflix on the console, and buy $75 worth of Cyber Clean to make a horrific lint-eating blob. Totally your call.
