What price convenience? Running low on a couple of items, I popped across the road to the convenience store, which is a few yards closer than my regular supermarket. My shopping came to £1.50. Not a lot, but the identical items cost me only £1 at my regular store, a difference of 50p. Again not a king's ransom by any means but on a bigger bill, say £30, the difference would be a staggering £15 more.

Even allowing for the cost of shoe leather or petrol in getting to the big supermarkets, it would take an awful lot of loyalty to do a regular shop at the convenience store.
