Flat Rate Shipping
Flat Rate Shipping: This method allows you to charge a fixed shipping fee per order, per item, or per shipping class, regardless of weight or distance. It’s useful for predictable, easy-to-understand shipping costs. For example, your store will charge $7 for every order sent within a specific zone.
Flat rate shipping simplifies the checkout process. Besides, it’s great for stores with standard packaging or uniform delivery charges.
