I was reading a discussion on Amazon.com about the $100 credit applied to your account with the purchase of the XBox 360 Kinect the other day. What they said there (and I remember this is also what I read on the product page before I checked out), is that it can take up to 4 days AFTER the item as shipped. It also just gets applied to your account and then you can choose to use it to purchase other things from Amazon.com. Hope this helps.
