How Per-Product Shipping can be used

Per-Product Shipping can be used in two ways:

Multiple Shipping Methods: If enabled, rates can be applied in addition to your other shipping methods. For example: If your store offered a bulky product that you wanted to set up with extra shipping fees, you could create a fee to be added to that specific product. If you had multiple items in your cart, two kinds of shipping would be represented in one cost — a) your default shipping costs for the other items in the cart, and b) the shipping cost of the bulky item.
Standalone Method: In this scenario the ‘per-product shipping’ is the default shipping method. In this case, all product costs are added together to form a single rate. When the Standalone method is chosen, no other shipping methods are offered.
