I have two tickets for Madness + Special Guests at the O2 Arena on 22 December 2012. The face value of the tickets are 107.50 (47.50 + s/c 6.25), and I am selling them for £90. The tickets are a couple of seats apart from each other, but are in a excellent block just in front of the stage (see image)! I can meet you in London a coupe of days before the concert to give you the tickets.
