Amazon: $20 Credit when You Buy Two Video Games = Donkey Kong Country Returns for $30

Right now Amazon is offering a $20 credit towards a future purchase when you buy two video games.  Some of the titles included are “hot” this season.  The most notable I think is Donkey Kong Returns.  This is a new title and I have been checking the price on this one for a few weeks and it has not dipped below $39.99.  With this promotion you would end up getting it for $29.99 after you account for the credit you will get.  Other titles include Epic Mickey, Call of Duty: Black Ops and more titles for wii, PS3 and XBox.
