Getting a wow CD key

[Volcom]

I got ahold of my friends wow Cds a couple weeks ago.
He's already using his key code so were, how, or who would know were I can get one? So I can register, or get a free 10 day trial
I'm really confused with it all lol
Like the key code gens for diablo lol(my last addiction)

To get a key code you have to buy the game. That's how easy it is.
