I'm not sure how this site works, but I've done something similar to this on a video game site where I requested game manuals and things like that.
I really hope someone has a Game Of Thrones Standard DVD slipcover they want to sell! In flawless condition of course. I don't care for much else :\.
I am crossing my fingers that luck will come my way and someone will in fact have one.
Reply to this thread if you're interested in selling, or even PM I guess.
