Economists and advertising analysts note that should a company need to increase the price of a product beyond the threshold price-point, it should only be done in small amounts. If a candy bar originally cost $1.99, then there is apparently little difference in making the new price $2.05 or even $2.25.
According to economists and advertising experts, when increasing a product's price beyond its optimal level, it is advisable to make only minor adjustments. For example, if an initial candy bar price of $1.99 is raised to either $2.05 or $2.25, the difference may be negligible.
