We would like to go to St. Andrews for a day while visiting Scotland in July. On the day we would like to go, the off-peak return tickets that are at the times we would are interested in have a note. One time says "Only 7 left" and the other time says "limited availability".
I believe that in talking about using the trains, people on this board (maybe it was TripAdvisor) said we can always walk up to the train station and buy off-peak train tickets. However from what I am reading, if I want to go on a specific day and time, I should buy these now.
