Buy the Sunday Telegraph (£2) this Sun (26 Aug) and enter the code printed in the paper, online at train booking site RedSpottedHanky and £10 will be credited to your account to spend by 31 Dec 2012.
The offer's available to both new and existing RedSpottedHanky customers and will be credited to your account within 72 hours.
Be quick though, as there's a limited number available and the offer ends when all the vouchers have gone or at 11.59pm on Sunday.
The code's valid on most major train operators but excludes Megatrain, Eurostar, and season tickets.
The detail: One voucher per person.
