Also, there's a couple of promo codes floating around that'll get you a 10% discount on the Two Together Railcard if you buy online.
Codes are LEAFLET3 or FRIENDS
I have checked and both are currently working. No idea how long they will remain valid for though.
Just got round to reading the leaflet I picked up from a station today (after I had bought the card on line at full price) and the
LEAFLET3 code is quoted as being vaild until 6th September 2014.
I assume as the card is not valid between 04:30 and 09:30 on weekdays it means any Rovers bought with it are similarly not valid during those periods. This would being it in line with, say, the Thames Rover which is normally valid from 09:30 or earlier unless bought with a Network Card and then it doesn't become valid until 10:00.
