It is huge. But so is the company so % is the only datathat matters.

On a store by store comparison. The average turn over of a local corner shop. Would not be able to support a family on 5% profit margins. They tend to function on 10 to 15%. And that is low compared to other industries.

As I pointed out. The issue is more. Tescos is so huge. 5%. Allows it to destroy all but other huge competition. So it prevents competition from ever getting a foot hold.

As all large corperation s will do when given the opportunity.
