A sale markdown refers to the reduction in price of a product or service during a promotional period. This decrease in cost is typically offered by retailers or businesses in order to entice customers to make a purchase. Sale markdowns can range from a small percentage off to a significant discount, and are often used to clear out excess inventory or to attract new customers. This term is commonly used in the retail industry, and can also refer to the act of marking down prices on items that are not selling well. Sale markdowns are a popular marketing strategy that can benefit both businesses and consumers, allowing for the purchase of desired items at a lower cost.
