From IGN's 9.0 review: "If you were at all disappointed with the first Scribblenauts, rest assured they fixed everything for the sequel." Exciting! The first one was a great idea, poorly realized.
So take your receipt in and tell them you want the discount. If they balk, bring in the system and "return" it then buy it again for the new price. Usually stores like Wal Mart will just give you the difference.
