London underground question - urgent

[pupuce]

I am off to London today... I'll have to take the tube at least 3 times in zone 1 (none will be return journeys IYKWIM)... maybe bus too.... all in zone 1
Do I buy ticket after ticket or is there a zone 1 travel card does that make it cheaper... when I lived in London I knew all the prices so would have known.... but moved 8 years ago so have NO clue.
Thanks

Leaving in 1 hour....

buy a travel card

I would buy a travel card. CHeck out this page:
travelcards

If you've still no reply from here. You can always ask at the station. At the big ones, there are special info people (in uniform)usually by the ticket machines.

The site isn't clear - what is off-peak? Would after 10AM be that ?
Does the travel card work for buses too or just tube?

and what is the price of a single in zone 1?

zone 1 travel card will work on buses & tubes. its by far the cheaper option. i thought after 9.30am was the cheaper zone.

last time i went on the tube, its was £1.50 single!!!

Sorted... single is £1.70, travel card is £4.70 - off-peak is after 9h30
Had to download PDF file to know all of this but it's done.
Thank you
