I have been saying this for years BUT you need to promote the right site ;)
When you find a site that can retain well then you can make more per sale AND not abuse surfers with pop ups and low trial prices that rebill at very high rates. If you run a high traffic free site with alot of bookmark traffic then I would not suggest sending your loyal visitors to these type of sites.
I like ftv. They have a solid site if you want to promote a non hardcore site. I recommend ftv to my members and it is one of the best recurring sites that I promote to my members.
Sites like mine, ftv, twistys, and some others work so hard to retain members and we do retain them
