4 X MUSE tickets for gig at The 02 arena - Friday 26/10/12 ?

I have up to 4 x tickets for the Sold Out MUSE concert at the 02 arena London on Friday 26th October 2012. Tickets are block 414, row M and are for sale at 150 each ticket. We are no longer able to attend and are having to pay a premium for replacement tickets.
