People who don't live near Underground stations can nonetheless take
part in the "Oyster Revolution" by using Oyster PAYG to pay for their
bus fares - the saving is considerable, as on Oyster bus fares are only
£1 - half the cash fare of £2 - and if you make several journeys on
buses during the day the daily price capping system means you'll pay a
maximum of £3, which is cheaper than the £3.50 cost of a paper
one-day bus pass.

But you'll probably lose more than that as your faulty Oystercard
breaks down taking your money with it!
