I'm 99% sure this is who we have dealt with in the past.

We currently circ Wii, PS2, XBOX 360, and PC games. In my personal
opinion, it is not all that necessary to have the booklet except in
the case of PC games, which often have the keycode for the game with
the booklet, in which case if the booklet is lost, the game is
virtually unusable. Players can figure out the game without the
booklet for the most part (I don't know a gamer who reads the
booklet). If the booklet gets lost, the game can still be played. I'd
charge a token fee if you wanted to replace the booklet, but not the
replacement cost of the entire game.
