Andy I had to book e-tickets for the return journey

from Hemel Hempstead to Northampton that were a little better value than our outward journey via the MML from Wellingborough to Harpenden. Mike chose to book his tickets on the day at the two origin stations. This is very laudable with him keen to support ticket offices but it does mean that he will be charged the most expensive walk-on fares that does not seem fare does it really?
