Can you buy car park tickets at a later date?

[Dog Burger]

Sorry, I'm sure this has been asked elsewhere, but I couldn't find a post. Do you have to buy car park tickets during the balance payment window or can you buy one later if you need to? I'm not as yet sure whether I'll be driving and don't want to chuck £45 on a ticket I'm not going to need. Any ideas?

You can indeed.

You can usually pay on the gate as well. I haven't ever done it but I think it's usually another fiver or so on top of the advance price so circa £50.00 this year.
