I have a spare ticket. Posted on another thread but here it is again
Preston - Glasgow: 12:54 - 15:17
Glasgow - Preston: 04:28 - 06:54
They are separate e-tickets for each journey which just need printing off. They have a seat reserved in both directions. Obviously whoever takes them will need to get to Preston but return tickets from Manchester to Preston aren't much more than £10 at the moment to meet the times of the Preston-Glasgow tickets.
Just checked the current total price from Manchester to Glasgow for those trains and it is £62-50.
The tickets cost me £21 but will be happy to get just a tenner for the return journey.
Please PM me if interested.
