Delivery fees are charges added to the cost of goods or services when they are transported from one location to another. These fees can vary based on factors such as distance, weight, and the type of delivery service used. For example, a restaurant may charge a delivery fee when bringing food to a customer's home. Many businesses, including grocery stores and e-commerce websites, implement delivery fees to cover expenses like fuel, labor, and vehicle maintenance. Some companies may offer free delivery for orders over a certain amount or during promotional periods to attract more customers.
