Stummbled on this page this morning and the first code "breakroom" worked for me on a game. Took 1.20 off the price so i only paid 80 cents for it. I can confirm that only one code per credit card but possibly if you use another one you may be able to get the discount.

BTW I got Resident Evil: ORC, I am a huge fan of the series but this game is just OK. Have not tried the multiplayer yet but the single player is ok and takes roughly about 4-5 hours to complete. However, there is a leveling system for each of the characters and tons of weapons to unluck so there is alot of replayability in this title. Def worth the 80 cents I paid for it this morning to play all day today and tomorrow before I return tomorrow night.
