I don't know how I missed this post until now. (sorry)
Old post I know but just for future reference there is no affiliate program for Clips4Sale.com and due to the business model there will never be a direct affiliate program for Clips4Sale.com. There may one day be a spin off where the % for payout is different so that it can accommodate affiliate split but at this time there is nothing in place.
What I can assure you though is that there is NO invite only affiliate system for C4S.
If ever you have questions feel free to contact C4S support -->
