I just got one of the best game deals i've ever gotten. I was at a pawn shop today, and they just so happened to have a copy of The Orange Box for $10, and it's in excellent condition. I'm going to play it soon.
No idea if it will be in shops, but it was SUPPOSED to come out on Steam like, last week, but hasn't. You can however buy a Steam activation code for it from the official running with scissors shop. That's what I did, just downloading it now .
