LONDON travel. what is the cheapest way to travel to work by Tube? Oyster Pay As You Go or any other ways?

Thanks
Hi we have got Oyster Pay As Go card. But we consider there have been a little ways we can have many of a oystare card?
specially when we transport Monday to Friday regulating Oyster card? Any suggestions rsther than than Pay As You Go?

Suggestions:


1. get a travel card on your oystercard. i get zones 2-5 and thats £17.50 a week (but i do get 1/3 off because im a student) so it should normally be around £25.
   since ive stopped going to uni i havent been buying my weekly travel card so ive been using pay as you go, and in one week i spent £20+
   so i'd say its better value to get a travel card

2. Oyster hands down,…

3. The tube

4. Go to the nearest tube station and ask about an Oyster for the year. You pay like 800GBP for zones 1-2-3 (I think) but it's for all travel the one year.

5. You already have the best option with you. Oyster is the best card
