Well now, a bit of news I learned about on Monday has already gone public! It seems as though both Amazon.com and GoGamer join GameStop in offering the 10% discount on Orange Box pre-orders, and the ability to join in on the Team Fortress 2 BETA.
Valve today announced that those who pre-purchase the PC edition of The Orange Box at Amazon and GoGamer before October 10th will save 10% off the regular price and gain access to the beta version of Team Fortress 2 for the PC.You can always find out more information by going to Steamgames.com. Now, I believe there will be one more retailer announced later this week that will be offering the same deal as these retailers.
