Thanks - I'm sure it was more than ^33 the last time I checked, but I must have been mistaken. Splitting tickets at Oxford actually makes it more expensive, so I'll probably just by the off-peak return.
Would it be OK to break the outward journey in Reading on this ticket? I'm guessing so, as I have to change at Reading anyway for Gatwick, so it wouldn't matter if I left the station for a few hours whilst changing trains.
Coach it then....to Birmingham & get the train?....
I did think about the coach, but I don't really travel too well on them! The small saving to be made isn't enough for me, on this occasion!
