For a limited time, you can get the 4GB Xbox 360 Kinect Bundle that comes with Kinect Sports for $199.99 from the Microsoft Store. The retailer has the Holiday Bundle version that also comes with Kinect Disneyland on sale for $199.99 as well but it is sold out unfortunately. We'd keep checking back if that is the one you prefer.
Halo 4 is also on sale for just $39.99 along with the open world racing game, Forza Horizon. Note though that Amazon has Halo 4 at the same price currently along with a $10 Amazon Instant Video Credit.
Also, while we covered this earlier, the Microsoft Store has the best deal for the new Xbox 360 Nike+ Kinect Training Bundle. While other stores match the $249 price, the Microsoft Store is the only one to include a two year Microsoft Assure warranty.
Free shipping is available for the consoles and games but tax is applicable in states that have a physical Microsoft Store location.
