My friend and I purchased 3 R4DS Revolutions from here and they all seems to be real, compared to the official statement made by the R4 Team. The delivery was very fast. I recommend buying stuff from this site.
About them changing their name, I personally like DealWoot more than GameByGame. But because the game sells merchandise that pertains to gaming, GameByGame is a better name. Either way, all the bes to GameByGame!
