Minimum fare (here in N Wales) is 1.30 for a single stop.
To town (perhaps 10 stops, and a longer router than walking, but an hours walkfor an adult) costs 1.70
Catching the train it's 70p single, 80p return, but only 1 per hour each way, where buses are 4 per hour (but rarely full, except morn/eve rush). As you can guess, train is my preferred option, only 'cos council subsidy makes the fares that low.
Sorry to read of the high costs so many have to face.
Jackstini this it was because the bus can be deemed adventure.
When I was young it was a treat to go on the open-top bus through Hove into Brighton. Always enjoyed looking out for a 'fork' shaped tree (3 prongs) in the Hove 'dead centre' (cemetery).
Must admit it was sometimes a real 'wake up' if they were short of buses and you had to go upstairs on an open-top on the way to school around 8.15 in the morning on a 'fresh' spring morning!
