2 x LADY GAGA TICKETS TWICKENHAM LONDON *GREAT SEATS* 9 Sep ?

I have two top priced lower tier seats for sale-in Block L23 Row 23 for the concert on Sunday 9th Sep. They were bought as a gift but the people can not make it now. Selling for less than face value-160 for the two, I have the ticketmaster receipt to go with them.
