Hi Bly, we don't pay on free signups, but you do get paid as soon as the person makes their first purchase of minutes ($20 expenditure for them). You get paid depending on the type of account you sent the traffic from, either 20% lifetime of the customer (pays out VERY nicely over the long term) or PPS which right now is on a sliding scale.
This is a special promotion scale that will last for the next 2 pay periods:
March 6-20 and March 21- April 5.
1-10 sales gets them $50 PPS
11-40 sales gets them $60 PPS
41-70 sales gets them $70 PPS
71-200 sales gets them $80 PPS
201-400 sales gets them $90 PPS
401-600 sales gets them $100 PPS
601-700 sales gets them $110 PPS
701-800 sales gets them $120 PPS
801-900+ sales gets them $130 PPS
Please let me know if you have any other questions!
