Purchasing the Master Chief Collection in December will net you $15 back

This has been practically the same deal that ran during pre-order. If you pre-ordered the MCC from the MS store you would get 15,000 credit, a sticker, and a special license plate frame (which I got). With this you only get the 15,000 credit. I'm not sure what the big deal is with this promotion.
