I ordered a xbox 360 slim through microsoft store but ended up canceling it and got this email today. I'm not sure if this is YMMV to those who purchased a 360 slim through the store or not... But here is what is says:
We hope you're enjoying the new Xbox you recently bought from Microsoft Store. Do you know how you can make it even more fun? Add the new Kinect. This amazing new technology allows the sensor to recognize your body and mirror your movements in the game, making YOU the controller. It puts you right in the center of the game like never before.
Not only that—but when you pre-order Kinect right now, you'll get a coupon for $10 off your next purchase of any product in the Microsoft Store*. There's a whole new generation of games that take advantage of Kinect—maybe you'll want to use your $10 off coupon to get one.
Thanks for shopping at Microsoft Store.
