The difference between elastic and inelastic demand rests in the product itself. A product with elastic demand is a product that consumers will increase their consumption of under favorable conditions. Soda pop is a great example. Soda pop sales increase around the holidays, when soda pop is routinely offered at parties. Soda pop sales can increase due to sales promotions, when prices are low
. compared to other beverages. A product with inelastic demand might be toilet paper. Regardless of price fluctuations, people tend to use and consume the same amount of toilet paper. Sales of inelastic commodities increase only when the number of consumers increase, or when consumers find a new use for the product. For example, if people found that they could use toilet paper in craft projects, sales of toilet paper might increase because of this new-found use.
