The Orange Box was already a ridiculous bargain but it's even more so this weekend. From Friday until Sunday, it's 66% cheaper.

Included in the Orange Box is Portal, Team Fortress 2, Half-Life 2, and both of the expansion packs for HL2. The deal is available in all territories. In the US, it'll only cost you $9.99 to purchase.

I have a hard time believing that any of you even remotely interested in this compilation haven't bought it yet. Still, there you go. Three GOTY contenders for only ten bucks.
