I'm rather suprised that this hasn't been brought up yet. Actually, maybe it has, but I did look around for it.
As you all know, many places put on sales for the holidays, but the real deals are right after. Here you can post all of the post-Christmas video game deals you find.
I'll give a few.
Steam- Bioshock $4.99
D2D- Dragon Age: Origins $39.95

There is already a thread about this, but it's all been taking place in the Steam Holiday Sale thread.

I see, I guess when skimming for a similar this thread I just passed over that one.
This is when I would normally ask for a mod to delete. Just try not to post on this guys.

Here's the thread:
