Well prepared via Oyster Online

I was very amazed when I found my Transport for London (TfL) Oyster Card today. It was hidden somewhere deep in my stuff. I logged on to Oyster Online and it's great what you can do on that site.. You can simply top up your Oyster Card via Credit Card.. And once you reach your favourite tube station your actual card will be activated again. I think that's a great way to prepare for London trips. So "Don't throw away your Oyster Card. You can use it again and again and again".
