We are a RevShare program, and while we have been experimenting with PPS, 100%RevShare, and our recent promotion listed on this thread and my sig:
http://www.gfy.com/fucking-around-and-business-discussion/843303-xlgirls-com-50-pps-50-revshare-bbw-tit-natural-site-pics.html which is a combination of PPS and RevShare. We feel that RevShare is best for both the affiliate and us.
The PPS model as mentioned above forces the sponsor to look at other revenue options, which in the end the consumer is the one affected by those actions.
For those that are not promoteing us. We are offering $50 PPS for the initial signup, 50% for the unchecked cross sale to one of our sites, and 50% for both websites revenue share for the life of the membership.
