Amazon is that incredibly successful website that sells just about anything and often at the cheapest price available. They have just patented a method of online haggling that will attempt to mirror a face to face exchange. The system allows buyers and sellers to make offers and counter-offers until a deal is reached or abandoned. To keep things in line a points system measures how each participant conducts themselves, so as to avoid things like false claims from suppliers and time-wasting from buyers.
The idea is only at patent stage but would add a new dimension to online buying if introduced.
