Isle of Wight Festival Camping Tickets (x 2) !

Hi! I have 2 x weekend camping tickets for the Isle of Wight Festival but due to another commitment that has cropped up my partner and I are unable to go. I paid 205 each for the tickets, this being the face value plus the booking fee, and would like to get my money back. However, I am prepared to look at any sensible offer. Many thanks
