I don't remember the manual being anything special. For that price, I wouldn't worry about it anyways.

Steam has a lot of titles on sale right now.. They also have Risen ($14.99), Duke Nukem Forever ($6.79), Portal 2 ($10.19), Dead Island ($26.79), DA:Origins Ultimate Edition ($14.99), and more.

Also, all DLC for Fallout: New Vegas is 50% off.
