Booking fees. Just another rip off, booked 4 tickets to see Peter Kay and had to pay a booking fee of £4.50 per ticket, thats £18 for foc all. You cannot go to a booking office and buy them so you have a choice, pay up or no ticket.
I booked the tickets through the First Direct Arena website which takes you to Eventim UK to book and pay, and when the comfirmation email came through the location of Eventim UK is apparently Amsterdam NL, so a Dutch company not a UK company as implied in the booking site name, a nice little tax avoidance scheme maybe?
