Following the weekend 50% off discount deal from Galaga Legions, Amazon.com is now offering several more Xbox LIVE Arcade games at a lower price than the Xbox LIVE Marketplace.
Doom is currently listed for $2.97 (41% less than on the Xbox LIVE Marketplace), and Pac-Man Championship Edition is currently listed for $4.97 (50% less than the Xbox LIVE Marketplace). Those are two great Xbox LIVE Arcade games. The previous Galaga Legions deal was only available for a couple of days, so move on these soon. They may not be available for that price for long!
