Amazon: '4 star' games for under 20 bucks include Dead Rising 2
Before you get too excited, know that the '4 star' referenced in Amazon's deal of the day refers to user reviews. So, while it includes deals like Dead Rising 2 for $19, it also includes Battle of Giants: Dinosaurs Strike and the DS version of Despicable Me (which only has 3.5 stars, cheaters).
