I have been asked to help a friend of a relative (so not someone I know personally) to buy tickets online for what seems to be going to be regular trips between Great Malvern and Dundee. She wants to know what website she should use, and is under the impression that I know all about these things as I do usually book any tickets needed for family and friends, but that is when I have specific details of their journey dates etc. As I use several websites for various purchases, all of which have their advantages and disadvantages, I am not sure what to advise her. I am wary of nominating any particular website as they all have their complications, and I'm not sure she could cope with split ticketing. For a total novice, what would be the best (i.e. easiest to use) website to suggest?
