Its been our experience that CJ is nothing more than overpriced hype.
They do have a lot of affiliates but, the costs in aquiring those affiliates simply arent warranted, you are paying for THEIR branding on YOUR site rather than sales from their affiliate base.
Save your money and go to
http://www.darkblue.com instead, lower startup costs and youll see a much higher return from ther affiliate base
