Heart of Wessex Day Danger at ^19.00 (^12.55 railcard - but not Two Together before 0930). Valid on any train after 0820.
Thanks - I must be slipping. Can't believe I missed the "Day Danger" trick.
RailEasy says ^35.90 with splits for 1 person and describes it as "cheapest" ... I'm sure the fine print indicates it's the cheapest they could find. Think that's an any route Swindon - Trowbridge rather than a "via Melksham" and probably a Trowbridge - Weymouth day via Yeovil when a Melksham - Weymouth is actually cheaper.
