Buy new Oyster card for London tube. 

Thanks so much for this video. I am visiting London next month for the first time and now I know how easily I can get an Oyster card from the machine.

This is Liverpool Street station, not "Liverpool Station". In Britain the names of streets, or railway stations names after streets, can not be abbreviated by truncation. That will result in confusion between Edgware and Edgware Road, Euston and Euston Square, Blackhorse Lane and Blackhorse Road, and Liverpool and Liverpool Street.

The fiver for the card is such a con, how is plastic five quid?
