Selling Prey for Steam

Hey guys, had this box sitting around and collecting dust so i am selling it, its just a CD key and it comes directly out of the box, i can prove i have the box and the CD key inside, I don't mind going first to trusted people or using a middleman, but don't expect if you are new and i don't know you that i shall go first, i am extremely picky with whom i go first to!
