Amazon just recently added PlayStation Network games for purchase. I don’t notice any deals, if you notice any let us know. A couple postivies I see are:

Easy way to give the gift of a PSN Game

No sales tax

Can use Amazon Gift Cards I assume

Don’t need to use the PSN Wallet

When you buy it you get a code that you redeem on your PlayStation 3. Do you think you’ll use Amazon to buy your PSN content? I wonder how quickly it’s updated. Still a great option though.
