Edinburgh Waverley to London Kings Cross - 30 June - departs 1330 ?

Hi, I have a ticket, which I will not be using. NB! YOU MUST HAVE 16-25 YOUNG PERSONS RAILCARD or other railcard. Travel date: 30 June 2012, train departs 13.30 from Edinburgh. The cheapest ticket for that day is now 37.95 with railcard discount (just checked), so I think 25 is a reasonable price to ask. I live in meadows but can cycle to meet you anywhere in central edinburgh. email me, leave your number and i will call you back soon.
