London To Edinburgh 4 Tickets For 22nd April 2012 ?

We are attending a Wedding in April but my mum bought two going up there tickets instead of returns so we would like to sell these. Unfortunately cannot sell separately as you need the master ticket to travel with a group of 4 but if you can get a group of 4 together? Selling Tickets as they are priced on the ticket because we just want our money back. £36.25 x 4 = £145 KINGS CROSS -> EDINBURGH 22.April.2012 16.00 hours. (4pm) Train Tickets My mum can meet anyone around Victoria train station or just contact us. Ask any questions Thanks for looking !
