Macgamestore updates promotion with 10% off option

The Macgamestore.com, run by Inside Mac Games, has updated their "buy 3 get 1 free" promotion today with a little twist. As the promotion goes, you can buy three games (it appears to be any three games) and either get Star Wars: Jedi Academy or Homeworld 2 for free. Today, they've added a third option: 10% off your entire order. Once you've added three games to your cart, you can apply the coupon code 10percentoff to receive your discount. Unfortunately, you can't use the discount on anything but games, but this is a nice refresher to their promotion which has run in its previous form for quite a while now. As of this writing, I don't see an end date for the current promotion.
