The event is sold out, can I still buy a ticket?

You can never be guaranteed a ticket for a sold-out event.
However, there are some options you can look into:

• Sign up for the waiting list or take an option on a waiting show, if that option is offered. Often some seats become available at a later moment. A well-filled waiting list may also result in an organiser providing an extra performance or concert.
  
  
• Buy a ticket from someone else, but not at a higher price than originally paid by the person offering the ticket. We recommend that you only buy tickets from people you know personally. Optional payment or shipping costs that are not included in the ticket price should not be charged.
  
  
• Look for the official website of the organiser or the venue. These websites always link to pages of official ticket sellers.
