All sales are non-refundable, including fees.
In most cases, we cannot exchange tickets between events. In the rare case that we can, we will ask you to place a new order for the desired event, and we will issue a refund for the old one. Service fees are non-refundable in most cases.
If you want to exchange your tickets within the same event, for tickets of a higher price, see: Can I upgrade my tickets?
If an event has its own refund/exchange policy, you'll find it posted in the event’s terms & conditions and/or your confirmation email.
