Bundle sales refer to the marketing strategy where multiple products or services are sold together as a single package at a discounted price. This approach encourages customers to purchase more items than they might have individually, often leading to increased sales for businesses. Companies often use bundle sales to promote new products or clear out inventory. By offering a combination of related items, such as software applications or food items, businesses can enhance customer satisfaction and provide better value, making it an attractive option for both sellers and buyers.
