Customers usually believe that companies’ prices reflect the quality of their products. If they promote their products as top quality, and only then, a high range of prices will match their ads branding. On the other hand, the market demand has a major impact over a company pricing strategy. If for example buyers’ demand for certain products doesn’t change as much as it changes in price, then companies can set higher prices, but if the quantity of demand decreases due to a change in price, the company will need to adapt its products’ prices.
