Upon searching, I couldn't locate a dedicated Steam thread, so let's start one now dammit! List any and all awesome Steam deals here!
This whole week Steam has been discounting the shit out of their games. Each day brings completely new sales, with tomorrow (11/29) being the final day. Today, among many other sales, you can pick up The Orange Box for only $7.50!! If you've been waffling on grabbing that (like me), now's your chance! But check it out...there are plenty of other great titles on sale too.
