This module lets you set up your shipping methods to calculate the rate as a percentage of the order's subtotal. It also offers the option, on a method by method basis, to use a flat rate instead. In addition, rates for each method can be set on a category and product basis. If rates are configured for the category the product is in or specifically for the product, those rates will be used instead of the rates configured for the method in the main administration. There is also a flag so that individual products (or all products in a given category) can be provided with free shipping. A domestic country may be selected and each method chosen to be available for domestic and/or international shipping destinations.
