[quote name='Josh5890']Do all of the PC games come with a Cd Key unless they are specifically stated as missing?[/QUOTE]
Yes, pretty much. But if it helps you any, what PC games are you interested in and I'll double check to ensure the CD Keys are there.
The only one I am pretty much 100% confident in is the Diablo Battle Chest that it is missing the Diablo II CD Key.
EDIT:
Added new bundles for PC games, pretty much the ones that no one wants for quick sales. So get them all for $1.00!
