cheapest/best/easiest way to get to London from Dorset?

[Mattk]

I live in Dorset and may need to go to central London next week for an interview. I was going to take the train but not having travelled by train in many years was shocked to see the cheapest ticket price is �46 and that means taking a later train.
Can anyone advise a cheaper way of travelling? If I go by car it will be cheaper but where would I park and how much would that cost? by the time I factor in car park price + hassle it may still be best to take the train.
Any help or advice appreciated.

thanks guys.
ive been looking at the location in london and they are only 3 or 4 underground stops from waterloo so i think i will bite the bullet and pay the extra purely for convenience' sake.

Use the coach to Victoria [ cheapest way to travel] and then the tube.
Dont come by car, the hassle of negotiating busy London and the cost of parking will get you flustered before your interview.
Allow plenty of time obviously. good luck.

If this is strictly a one-off and of some importance, then you must use the train to keep your sanity. I travel regularly from Bournemouth to Bethnal Green and this journey is so straight-forward, quick and reliable it is just not worth contemplating any other way.

thanks again.
have checked coach timetables and this would involve changing en route and is considerably longer in duration than the train.i did consider driving my car to the edge of london and then taking the train in but as said above altho more expensive, the train is far more convenient....in this instance anyway!
