so you will take skype from cj and get it to CB and start selling their subscription packages or something? hehe.
I think you may be missing something, CJ and CB are quite different networks.
I'm a little confused as to what you're asking, do you mean ClickBank --> you'll promote their offers in Adwords. (if so yes that'll work)
Or you want to do CPA Arbitrage, Promoting the CJ Product through clickbank, this will also work but its a fair bit of work, requires atleast a 10k investment, and most likely CB will just use their own CJ account anyway.
Cheers
