Hello, I understand the Gatwick train goes to Victoria station. I will be landing at 5.10pm on August 14th to Gatwick and wondering if I need to book ticket now (as I know sometimes its cheaper in advance) or can I just buy when I get to station? I don't want to risk buying now if it will be same price in case flight is delayed.
Also if I do just purchase before I travel, would I buy an oyster card and put money on that, or will it be a separate ticket and I can just buy oyster card when I get to Victoria station?
Thank you in advance for help :)
