It is indeed but sadly my nearest Tesco is a good 30/40 minute round trip and I never seem to be "just passing". I live on the outskirts of a city ... tis technically a city but more like a big market town in reality ... but my choice of supermarkets is pitiful. I have a Sains a quick drive away but nothing else for flipping miles.
I did have a small Budgens about 10 minutes away, right by my office, but that's closed.
