Alton towers tickets 15/09/2012 !

i have two sun tickets for alton towers dated 15/09/12. i am now un able to use these tickets so ive listed them forsale so i can use the money to put towards buying tickets for a different date. each ticket is worth 45 if you purchase on the door and 27 online so 30 for two is not really asking very much. i will be working most of the time so send me a txt rather than call and ill get back to you as soon as i can or email me thanks for looking
