Green Day - American Idiot Musical Southhampton 12th October early show 2 tickets in Stalls! ?

Hi, I have two tickets in the Stalls for sale for American Idiot on Friday 12th of October, the early show at 5pm at the Mayflower theater in Southhampton. I mistakenly bought these for Friday night instead of Saturday, so now I have 2 useless tickets. Face value is £34.10 plus fees each. Will mail them first class anywhere in the UK upon successful sale. Thanks,
