Shipping rates apps allow you to offer different rates for different groups of products and locations. For example, you can offer free shipping for some products, carrier rates for other products, and rule-based rates for others. You can also set unique rates based on shipping zones, choose to restrict products from zones or add customs/duties percentage, which is particularly useful if you plan to ship internationally. You can also create custom rules, such as setting rates to free shipping when a customer orders over a certain amount.
