A price war is a battle between companies to offer the lowest price for their product or service. However, there are several other ways to describe this phenomenon. "Price competition" refers to the process of lowering prices to compete with other companies. "Discount war" is another term that refers to a price war where companies offer discounts to attract customers. "Price slash" means to cut prices drastically to gain an advantage over competitors. "Price undercutting" is when a company offers a lower price than its competitors to gain market share. Whatever term is used, a price war typically means increased competition and lower prices for customers.
