This contribution allows the shop owner to assign a shipping method to each product. This will allow you to have an order containing items that ship by multiple methods and still calculate an accurate shipping rate. One product could ship via UPS while another can be shipped via FedEx. All of the following (and more) are possible:

1. Most products ship by a selection of standard shipping methods, but certain large and heavy items ship by truck.
2. Products ship from one of two or more locations.
3. Some products ship by a selection of standard shipping methods, some must ship by a specific method, others ship directly from several different suppliers.
4. Any combination of the above.
