hey, ive read loads n loads about oyster cards, but im stilil not sure if i want to get an oyster card for a bus, do i jus got to a shop that sells them and buy one? or do i have to order it??
I think if you buy a monthly travelcard, you'll get it on oyster card anyway now - part of the scheme to speed up rush hour I think.
I don't think you can get them for weekly travelcards or less, but I'm not sure.
They also do pre-paid things where you put a certain amount on your card for a journey, and then just put it on the yellow reader at the start and end of your journey, but this seems a bit odd, 'cause what if you make more journies than you intend?
Anyway, hope that helped.
If you've got any more questions, go to a tube station, that'll answer your questions for you.
Edit: Oh yeah - if you're a student at a uni in london, you can get 30% off your travel, if you apply for a £5 discount card. The forms should be available at your SU, and it'll take about 2 weeks to come through the post to you.
Weekly is £4 and monthly is £15.40
train/tube/bus is SO ridiculously expensive for a crap service
