Are you not paying for premium sales in PPD plan, as website sales referral?
The thing is i have ppd plan, added website, and 3 sales, none for which i was paid. Or are you simply not paying for those 1$ trials? Sales details show 0$, neither they are counted as website referral (which is weird since they did came from website, hard to image none of 3 people that bought did not have cookies. )
It was probably mentioned before, but i don't have time to search through for it. regards.
