Kyle MacDonald is a Canadian blogger who bartered his way from a single red paper clip to a house in a series of online trades over the course of a year. MacDonald was inspired by the childhood game Bigger, Better and made his first trade, a red paper clip for a fish-shaped pen, on July 14, 2005. He reached his goal of trading up to a house with the fourteenth transaction, trading a movie role for a house.
