I have two tickets for the evening performance (7pm) of A Christmas Carol on 26 December but unfortunately will now be out of London on this date. Seats F9-10 Bayliss Circle.
They were bought via TodayTix and are available for collection from the box office 45 minutes before the performance (see attached) - I just need to change the name on the ticket. Selling them at face value, so £20 each. DM me if interested.
