<{POST_SNAPBACK}>When was the last time you went on the Underground ?
An adult single (daytime) Zone 1 fare for one stop paying cash is £4, however, if you have a Oyster Card its only £1.50

three years ago but it works on a zonal system so 1 stop in zone 1 is £4 without Oyster but 20 stops in zone 1 is £4 without Oyster, so long as you don't exit the barriers any station. In theory you could visit every station in zone 1 for £4 (without Oyster).
