Domination Dollars
 

Academy's Domination Dollars is a fantastic affiliate program if
you have an adult, fetish, bdsm, or femdom website. Members join for
$50-$75 US per month (which they're always happy to pay) and you get paid 50% of that ($25-$37 US). Plus you get paid 50% on all recurring memberships and since many members have remained for years you can make alot of money.
