i made some cd releases a few years ago, the biggest one was limited to 1000 cds. the prices for b/w booklets in this unit range is ridicolous enough, i can't recall exactly but i think for a game booklet in the millions of units... maximum 1 cent per unit. assembling even less.
a normal full coloured 16 page booklet, music cd, jewel case, batch of 500 costs like 4$ per cd.
leaving out the booklet is nothing more than bullying the customer because the publishers sold their souls to investors.

must-have-list for platforms i don't own yet:
WiiU: Donkey Kong
XBone: Dead Rising 3, Ryse
