For those who don't already know, there's a ubiquitous 25% discount code currently in effect at http://www.greenmangaming.com/?gmgr=colocino:
GMG25-EVFWS-4Z4ZN

And that brings it down to $45, but after purchase you get an additional $2 credit if you use somebody's referral link.
People can feel free to post their own here as well, but mine is either the above link or this one: http://www.greenmangaming.com/?gmgr=colocino

And that give both you and I $2 credit. Be sure to use the code pasted above for the 25% discount while checking out.

Dishonored for $43 is a nice deal, imo.

There's already a GMG thread here; http://www.gamesas.com/topic/1415362-green-man-gaming-keys/
