If the festival you are attending requires a ticket (whether free or for a fee), you will have multiple routes to buying a ticket.
When in doubt, you can always click the “Ticketing” menu item at the top of any page. This page shows you the full list of tickets available for your festival.
You can also start the purchase process from any event page. If you do not yet have access to that event, you can click the “Tickets” link to see the list of tickets that grant you access to that event. Select one of the tickets and you will be brought to the Ticketing page with your ticket of choice already filled out with a quantity of one.
For festivals that allow on-demand viewing/listening of selections, you can also identify the right ticket directly from the selection page. Simply click the “Viewing Options”/"Listening Options" link. This action will present a dialog that lists the different screenings of the selection along with any on-demand options. Select an option and that will take you to the event page where you can select the proper ticket.
On the Ticketing page, you can enter a discount code if you have been given one as well as add a donation in some instances.
When making the purchase, you will be prompted for your credit card information on checkout if there is an amount due.
You can see the full list of tickets you have purchased on your profile page. In addition, you can transfer tickets to other users from that page.
