You do need to stick at it. Drove me nuts trying to get the discounted tickets page up. Just kept hitting the "from £6.60" button till I got there, and I was left at the end wondering if it had gone through. Guess I'll have to wait to see if tickets arrive or money comes off card. First tiime I have bought on-line. Usually look them up and then purchase in a station so I know what I want and get what I want - no missing reservation bits.
