London_Calling
Pleasant and unpatronising
It really depends on the journey.
On longer trips it's usually better to split the journey; like a return from London to just outside London, from there a return to Exeter, and a third return from Exeter to Penzance - it's mad but you can save huge amounts that way rather than booking the whole journey in one ticket. Also, it's always more expesive travelling 'via London'.
The other tip is - if you know this far in advance - book up to 12 weeks before you go as that's when the train companies are legally obliged to publish their timetables and offer fares. It's when the biggest discounts are available.
