All payments go directly to the PayPal or authorize.net account that you specify, immediately. With PayPal, our commission is automatically taken at the same time (although we never, ever, have access to your PayPal account). If you're using authorize.net, our commission is billed to you in a monthly basis.
Important: Please ensure that you have either a Premium or Business account with PayPal. It's free to upgrade. See above for instructions on how to do that.
