Balzac was good at buying things at its lowest price. One day he wanted to buy a vase in a shop window that was much more expensive than he could offer. Not being able to make the shopkeeper cut down its price very much, he left without further talking. Collecting a half dozen of his friends, he explained his wish to them and they worked a plan. The first would enter the shop and make an offer, lower than the marked price. Not getting the vase at his price, he would walk out. Shortly after another would enter and ask for a price lower than the first. In this way, each of the others would offer a price lower than the one before, and the last of his friends made a great effort to attempt to get it at the lowest price. Before long Balzac himself would return, offer more than the last two or three persons made and trust to luck. The plan worked--- Balzac got the vase at his price!
