When is it best to buy the cheapest ticket from London to Wales?

Question

Hi,

I need to go from Slough on August 25, around 2:30pm to Port Talbot and i will be leaving Port Talbot on August 27 in the morning. When should i buy my tickets (for a friend and I) for the train? I am currently in Canada. Should I buy them when i arrive in London, or is it cheaper to buy them online?

Thanks for your help!

Answer 1

If you buy them on the day of departure it will be (using today as an example) £81.50.

If you buy them in advance for the dates you need you can get them for as cheap as £11.50. 2.30pm is kinda peak travel so you're probably looking at about £25-£30 for the time you wish to leave.

So yeah, definately book in advance online. You can pick up your tickets from a machine at the station. You will need your confirmation number and the card you paid them with.
