Frank Woolworth was born in Rodman, New York, in 1852. His family were very poor farmers, and there was never enough to eat. Frank decided he did not want to be a farmer. He took a short business course, and went to work as a salesman in a large city.               Woolworth realized he had a natural skill for showing goods to attract people's interest, but he soon learned something more important. One day his boss told him to sell some odds and ends ( ) for as much as he could get. Frank put all these things on one table with a sign which said FIVE CENTS EACH. People fought and pushed to buy the things and the table was soon cleared.               Soon afterwards, Woolworth opened his own store, selling goods at five and ten cents. But he had another lesson to learn before he became successful. That is, if you want to make money by selling low-price goods, you have to buy them in large quantities directly from the factories. Once, for example, Woolworth went to Germany and placed an order   for knives. The order was so large that the factory had to keep running 24 hours a day for a whole year. In this way, the price of the knives was cut down by half.                  By 1919, Woolworth had over 1000 stores in the US and Canada, and opened his first store in London. He made many millions and his name became famous throughout the world. He always runs his business according to strict rules, of which the most important was: "THE CUSTOMER IS ALWAYS RIGHT."www.ks5u.com The price of the knives was cut down by half because   _  .
