We offer 5% at
PimpRoll so there is no required number of sales, and it lasts forever. How could you ever be sure someone will pay you 50/50 forever? I wouldnt encourage such 'incentivized' referrals. Just find someone who seems helpful and message them for a referral link or something is what I'd do, and what I've done.
If you'll be hitting up support every day, joining through my link would be cool, lol
