Cheap return travel from LONDON 26 June to 25 July

Thanks to Martin's Money Tips (www.moneysavingexpert.com), I have been alerted to the Oyster Card and Freedom Pass Voucher offer (http://www.daysoutguide.co.uk/oyster-voucher) which starts tomorrow (Saturday 26th June 2010) and runs until Sunday 25th July.

Basically, Oyster card holders can print a voucher which gives them a walk-on fare of £15 return from London to Birmingham using either Chiltern Railways or LondonMidland. Oyster cards can be obtained by anyone on demand in London or by post for a refundable fee of £3...

The ticket is for off-peak travel only BUT as Chiltern do not have peak-time restrictions on journeys from Marylebone to Moor Street / Snow Hill the voucher is giving you better than half-price travel on this line (don't forget that you can't return on trains which arrive in London before 10am Monday to Friday). Better still, the ticket is valid for the normal period of a month...

LondonMidland off-peak services from Euston are from the 0846 Monday to Friday; as with Chiltern, you can't return on trains which arrive in London before 10am Monday to Friday. First class returns are available for £30 and I assume are 'off-peak' too; both classes are monthly returns.

NOTE these tickets have to be purchased from the booking office of a National Rail station in the London area.
