Hard to cashout at this GPT if u join without referral, i already join this program almost 5 months and till now not reach minimum payout beside no referral this program rarely send me e-mail Ad :)
Lately they have been sending more ads... On an average I get 10 a day... it does take a bit to get to $25 payout but if you have a couple referrals its easy..
When I go into my inbox on the site I always have 10 ads a day.. I'm not sure why your not getting all of them... I swear ... I was just there and there were 10 waiting for me.
