Once you reach 5 tickets sold thru your unique URL, you will be eligible for a refund. The credit will go back to the card you purchased tickets on. They are processed on the 15th of every month. For example, if you bought tickets on the 1st, shared your link and your friends bought tickets so that you met the 5 ticket threshold on the 8th, then your refund will be processed automatically on the 15th. You will receive an email notification about the credit back to your account.
