I just checked mine and they're selling it for $40. Lots of other people have been successful too. In-store only. There doesn't seem to be any real pattern to what stores are doing it, you'll just have to check with them to find out. Pretty slick deal for a game that literally just came out.
Moral: Never buy an Ubisoft game at launch, unless it's Rayman Origins or Beyond Good & Evil 2 or something. Then it's cool.
