Cj vs. Clickbank

I have just finished writing an ebook which also includes a video.

I am in the process of having the product approved by clickbank...

What is the difference between CJ and Clickbank and which one of those
would I be able to make the most money.

I know that CJ charges you but I have not been to their website to look at
the cost, if I can afford to pay those costs... would I make more money
with CJ...

Thanks
Brian

The upfront fees you have to pay CJ as an advertiser are HUGE.

plus you need to prove 50k a month in sales to get approved for cj. they don't want start ups.
