Today, Amazon has opened an Xbox LIVE Arcade storefront through which Xbox 360 users can buy XBLA titles. You pay the cash for a redeemable code, and then you use said code on your 360. We were hoping that Amazon might shave a bit off the purchase price (as they do with LIVE Gold subscriptions), but sadly, such is not the case. Then again, Amazon should make it a lot easier for friends/family to buy you digital games, which is a nice perk. [Amazon via Kotaku]
