Welcome to the Whatsonstage.com Ticket Exchange. Our aim is to provide a safe, secure and guaranteed place for theatregoers to buy and sell unused tickets. Before advertising tickets for performances you are no longer able to attend, we advise you to check with your point of purchase about their returns policy. Most subsidised theatre companies in particular – including the Donmar Warehouse, Royal Shakespeare Company and National Theatre – offer exchanges and/or refunds and reselling tickets may put you in breach of their terms and conditions. The resale of concessionary tickets is forbidden as these are limited to those people who qualify for such concessions.
