Charles Shaw once started a winery. He owned it with his wife and 5 children. Due to the financial troubles associated with the winery, his wife wanted a divorce. As part of the divorce settlement, she acquired the winery. As a result of how hurt he was by the divorce, he lowered the price of the wine to $2 thinking she wouldn't make any money and never get out of the pile of debt the winery had cost them. Little did he know of how successful it would be.
