Or join the 21st Century - get a parking app.
Takes a few seconds once parked - no change needed or messing about with meters and no ticket required.
I did that last year when I went to Cornwall and then had to change plans when I realised I couldn't get a phone signal in half the carparks!
Also find it a bit frustrating that there's so many different ones - currently have MiPermit, RIngGo and JustPark. Northants Train station use Saba (but that's right rip off and last time I used it you can only pay in 24hr full day blocks)
