A megastore is a large retail establishment that offers a wide variety of products under one roof. These stores typically cover thousands of square feet and can include items such as groceries, clothing, electronics, and household goods. The goal of a megastore is to provide customers with a one-stop shopping experience, making it convenient for them to find everything they need in one location. Many megastores are part of larger chains, such as Walmart or Costco, which allows them to benefit from economies of scale. This means they can often offer lower prices compared to smaller retailers. Megastores may also feature additional services, such as pharmacies or restaurants, enhancing the shopping experience for customers.
