Seat holders return their tickets for Centre Court, No.1 and No.2 as they leave the grounds. These go up for sale after 3pm at the Resale Kiosk beside The Hill. They are a bargain price: £15 for Centre Court and £10 for the others, which goes to charity. But the queues can be very long. The resale queues are waiting for the original seat holders to leave the courts and go home. And on a lovely sunny day with great matches, they might not!
