At the moment, when you buy an Xbox 360 with Kinect from Amazon, you'll get a $100 credit. Plus all of their Lightning Deals" today will be on video games. This is the 4Gig model which means that you'll probably need to spend some of that $100 credit on a bigger hard drive, but still the Kinect bundle costs $299, and with the credit, you'll essentially be paying $199 for it, which also includes the Kinect Adventures game.
Even if you don't care for motion gaming, and already have an Xbox, you can still grab some of the Lightning Deals that are running all day long. Currently they have Excerbeat for the Wii, but there will be seven more sales running throughout the day. We don't know what they are, but Amazon has given us some clues. If you think you've solved a clue, post in the comments below.
