SAN JOSE, Costa Rica - Adult dating site IwantU.com is offering affiliates $100 per sign-up on sign-ups during the month of June.

The promotion applies to IwantU's $3.95 trial prices as well as to the site's regular per-sign-up rates.

"We have reached a point where our retention of our members is long enough that we can afford to pay $100 per sign-up and still make a profit," said Director of Operations Keith Bussey. "That's truly all there is to it."

IwantU offers 12 niche sites, along with private-label sites. The affiliate program also pays out on a revshare basis.
