Instructions:First post so please be kind!
At Sainsbury's at Great Western Road Retail Park (Glasgow) I noticed a sign saying that you could get a voucher for return train travel to anywhere in Scotland for £15 for 2 people (£15 for each person) with any purchase (potentially a big saving). I had to ask at the checkout for mine. There were restrictions Dunblane pops to mind and expires on 18 December 2008.
I'm not sure if this is available throughout the country but it looked official (assuming this is only available in Scotland) Unfortunately I missed out as I could have used this for a trip to Elgin, but I hope this helps someone!
I'll see if i can scan and post the voucher but i've left it at work :-/
