If you don't have the Orange Box, now's the time to grab it! Steam's Weekend Deal
this weekend is the OB for 66% off, which translates into the price being US$9.99.
So that's Team Fortress 2, Portal, Half-Life 2 + Episode 1 & 2 for just under AU$15 or so. Definitely no excuse not to grab it if you've been meaning to pick them up! promoted/edited forum item
