Do you only need a case? Or are they charging extra money for the cover art and booklet missing?...if so, shouldn't they have to go get a case, booklet and coverart for the game before they can resell after buying from you? If its just the case, you can easily pick up a case...or hell, just take a case off your dvds or something.

I cant really blame them though, I wouldnt pay as much for a disc only game as I would for the full complete game.
