What is a promotion code and how can I redeem one?
Every organizer of events with ticketing can create promotion codes and then send them to people who can get a discount on the purchase price or gain access to ticket categories that are only visible to people with a code. If you have been sent a promotion code you can redeem it on the corresponding event page when buying tickets.
