Another code that will expire soon:
Razer GOG deal-expires Dec 31,2014
-80%off the following:
Guacamelee Gold Edition
Giana Sisters Twisted Dreams
Giana Sisters Rise of the Owlverlord
Anomaly Warzone Earth
That is, you still need to pay for stuff but it's 80% off! Btw, you can pick and choose anything you want from these games on the redeem screen.
Just reply to this post and I'll PM you the code.
I also have a Witcher 2 code that expires the same day, but I doubt anyone will want that, since it is provided in abundance...
