Where to buy a cheap and legit Call of Duty cd key?

You can use the administrator key codes, which are free, and unlock the game, legally, it was made for the Devs. Look and see if they have any.

Try going to the developers website and checking if you're able to buy a key from them. Didn't your game come with a key?
