Just discovered that there is a Bus Link ticket from my town of Cullompton (which has no rail station) to Tiverton Parkway. The origin code is H015 and the destination code is 3474. The options are a day single of £1.30 (on the bus the fare is £2.10) and a day return or period return at £2.10. (a) Can I go to the ticket office (probably at Tiverton Parkway) and ask for this to be added in advance to my tickets (I usually by advance tickets to Reading, London etc and (b) has anyone used these and encountered grief/problems on the buses with these (Stagecoach Devon)?
