My Easter present to you all is the addition of daily caps to the results returned on my fare finder. To access that just click on the yellow button at the top of every page of the site. Or, particularly if you are on a mobile phone, you can see a standalone version at https://oysterfares.com/off.
I have included the caps on every result, even though they are usually the same. I still live in hope that the 2-6 and 2-9 daily caps may one day return. If you’re curious, try Finsbury Park to Hackney Central as an example where they are different now.
