@ensa, some partners have possibility to set-up prices for they files individually.
Just re-checked this and if purchase come from such file, you receive 50%.
In "Sales" report you will see original premium price, and at "By period" report you will see your cut.
You can test this at any time. Just PM transaction_id me and i will refund your test payment.
@lawina, there is no mechanism to set-up PPD rate individualy. Rate regulated by system.It depends on the traffic quality; i.e. the number of Premium sales in relation to the number of downloads.
