Amazon just launced their own PlayStation Network Store this morning. 

Similar to the Xbox LIVE store, when customers purchase games, they receive the downloadable code.  You can guarantee that we will get to enjoy good deals and discounts!

To celebrate the launch, they are offering a free Playstation Network game with the purchase of a PS3 120GB console or PSP!
