Recently I discovered a site called MoreNiche. This is an affiliate site which actually pays you $30 for a sign up, or $20 + 5% of the referrals earnings for life! The great bit is, sign up is absolutely free, so you can really make tons with this program. The only catch as far as I can see is that you can't creat incentive-based sites, so the user has to be really interested to be valid.
I highly recommend that you check out this site. You don't have to pay anything, so really you can't lose. Tell me what your experiences are, I'd love to hear whether anyone else has used MoreNiche, and if so, how you like it.
