This promotional offer, commonly seen in retail settings, allows consumers to purchase three items while paying for only two. Typically, the lowest-priced item is free. For example, a customer selecting three novels of different prices receives the least expensive one without charge.
Such promotions stimulate sales by encouraging larger purchases and introducing customers to new products. This strategy benefits both the retailer and the consumer. Retailers move more inventory, potentially boosting profits, while consumers acquire additional items at a reduced overall cost. This type of offer has a long history in retail, proving effective across various product categories, including books.
