Microsoft Stores are now selling the 4GB Xbox 360 bundle with a Kinect sensor for $99. As with all too-good-to-be-true offers, however, there is a catch. To get that price, you have to sign up for a 2-year contract for Xbox Live Gold at $14.99 a month. Considering the console normally retails for $299 and a year of Gold is $60 (but can be found for much less), you’ll wind up paying a lot more than you would by just buying the console outright.
