Well if so, by now you should have your $15 promotional credit available to use, and what better way to spend it than by putting it towards the second biggest game to release this month, The Witcher 2? Sure this is only relevant to PC gamers, but those gamers will be interested to know that Amazon have already discounted the retail version of the game from $49.99 to $44.99 and even better, the digital version to just $39.99. Slap on your $15 credit and you can get what is sure to be this years greatest PC RPG for just $25 bucks.
