Almost all of us have visited a supermarket, but why do we go there? OK, the obvious answer is 'to buy things', but why do we go specifically to a supermarket rather than a local 'corner store' or somewhere else? Is it good that we go to a supermarket, or perhaps we should be shopping elsewhere? The answer probably depends on who you are and what you think about a large number of different issues such as 'value for money' , 'convenience', 'fair trade', 'food quality', 'freedom of choice' and so on.
