Big-box stores are large retail establishments that offer a wide variety of products under one roof. They typically have a simple layout and are designed to maximize space, allowing them to stock a large inventory. Examples of big-box stores include Walmart, Target, and Costco. These stores often provide lower prices due to their bulk purchasing and efficient supply chains. Customers visit big-box stores for convenience, as they can find groceries, clothing, electronics, and household items all in one location. Many big-box stores also feature additional services, such as pharmacies and photo centers, making them a one-stop shopping destination for families and individuals alike.
