Some events have upgrade items for sale like parking passes, camping passes, merchandise or concessions. Some upgrade items may be required, so please fully read the event description. These items do not incur a Sellout fee, though payment processing fees apply to all purchases.
If you forgot to add a desired upgrade, you can always add upgrade items to an order while supplies last. To add an upgrade post purchase, you can either contact the event organizer or use the chat feature to speak with a Sellout team member.
