At the lowest price for jeans, consumers will demand the most jeans, and producers supply the least jeans. If there is a low price on jeans, consumers are more likely to want to buy that product because it has become more affordable. However, if the demand for the jeans is high because the prices are cheap they likely are not supplying too many of the jeans because the profit margin is not great. Suppliers want to produce items they want and make customers happy, but they also want to make a profit, too.
