Premium sales were never counted from day one. Before my departure 3-4 years, I have attracted over 200 premium sales but I received not a penny from them. But that's alright, not everyone used its service for making $$$.

There's another thing, if you enter your paypal info incorrectly, they will simply ignore your payout requests while you ponder when the hell they are going to pay. I think it took me over 2 weeks waiting and waiting and waiting....until I emailed them and they said my paypal account was incorrect. It was my first time using Paypal and I was pretty stupid at the time. I also heard that if your personal info does not match the info in Paypal, they will ignore your payout request too. This however was unconfirmed.
