Yes oyster on the tube is a LOT cheaper than actually buying a ticket - I just have one for the odd occasion I need to make a tube journey.
The real rip off in the UK is the rail season tickets nd the above inflation increases. For a lot less than I will be paying to travel 60 miles to London in Germany I could get country wide travel !
Commuter tickets into London are crazy. I had to work with a client on site the other month and stayed in Crawley (about 30 miles outside of London), I paid £22 to get into London that morning. In the evening I travelled across the country home (about 150 miles) for £15.
