I have just booked up to go to Hartlepool on Grand Central next week. Mistakenly, I booked via Rail Saver which is advertised on google search as 'railsavergrandcentral'.

Anyhow, I have paid a £4.68 booking/card fee on top of the £77 ticket - I just assumed they had been introduced and thought nothing of it.

I then re-checked and the main Grand Central website wouldn't have charged booking/card fees

Only £4.68 but i'm really hacked off and just thought i'd warn others who may make the same dozy mistake
