Hi all. I noticed recently that the fares for Chilterns services on the London Marylebone to Oxford route seem to vary throughout the day: some services are £15.00 advance single, select others are £37.60! Same day, same service, same type of ticket, and doesn't seem to be linked to the time either.
Does anyone know why this is, and how to know which services will be the cheaper ones? I only ask because if you take two advance singles for the cheaper services it turns out to cost a fair bit less than an off-peak return.
