* Registering your credit card does not charge your card at this time. Preauthorization of your credit card makes purchasing or checking out at your event easy and quick. By registering (or preauthorizing) your credit card here, you're giving the event organizer permission to charge your card for items that you agree to purchase or donations you agree to make while at the event. Service fees will be applied in addition to any total if you have opted in to cover those fees above.
