I'm not sure if I'm posted to post this link, but actually I don't want do advertise, I just wanna share this website with you guys, some friends showed it to me and looks like an awesome way of buying CD Keys, they have really cheap prices and they also do some giveaways sometimes. I just bought Just Cause 2 for Steam for 7€, received the key almost instantly, I totally recommend them. Has anyone bought from them too? It seems they also sell GW2, SWTOR, The Secret World, etc. I might buy SWTOR for only 18€ soon.
