Have used since 10/25. I purchased gold membership $4.99 for 1 month. You can either purchase credits or earn them by joining or clicking other programs. I purchased 50 credits for $10. With gold membership you also receive random referrals. So far I think I have got my money back from this site. I have received 15 random referrals, traded 50 credits for a "green" on cashrewards.git-r-free which I cashed out for $40.
