Excellent cdkey shop because of good service and cheap price.
I started to keep one eye on gamekeysbuy.com from last year, my friend recommended me. During 2012 I had ordered from them more than 10 times. I paied and get their email with cdkey the next day. Sometimes I left message to them via skype to ask for new game's information and also always got their feeback th next day. Their price is really cheap but with woderful afterservice.
