Use that Oyster Card more

Well used Oyster card; taken by Nico Hogg. Used under licence.
Annie Mole, author of the rather fine London Underground Tube Diary, mailed me the other week, idly wondering whether I was updating my Oyster card calculator.
I discovered a while back that if you use a prepaid Oyster card, rather than buying a season ticket, it’s cheaper in many instances. Indeed, if you only travel to work and back on your Oyster Card, it’s a pretty poor deal if you buy a season ticket; which came as a surprise to me.
For example, my travel pattern would mean that buying a monthly season ticket would end up £280 more expensive than using a normal pre-pay Oyster card. Mind, that’s nothing to paying cash every time; that would be £729 more expensive!
The script’s now updated - the latest version uses April 2007’s prices. Give it a play and see if you can junk the season ticket - not least, knowing that the strikes are apparently coming tomorrow, it’s useful information. The code’s all JavaScript, by the way; pretty shoddy stuff at that, but then, I was learning when I did it.
