I have sold several domains from their platform--
Once they received the payment the timings for pay out are 10-21 days.
They will take 5usd or 10% as their commisson which one is hire and if payout is via paypal then no service charge would be deducted via paypal i.e. If payout is for 100usd then you will get 90usd as a whole.
Actually you both are half right.
30% commission if purchased via the registration path.
10% commission if purchased through the auction section.
