Blimey. I can't remember what I paid on the Coventry to London coach, but it must have been quite a bit more than that as I used to hitch a lot then too.
Later I did the Birmingham to Lyon by coach quite a bit. Took ages.
I think that was a special offer tbf. I once went from Darwin to Melbourne via Mount Isa, Cairns, Brisbane and Sydney - there were some long journeys there, particularly with a very sunburned back
