This is just one example of what you can do to customize your shipping calculation for your checkout page. This example provides a combination of prices and weight/package types to come up with a final total for shipping. In this example, combined products of one weight/package type and price become one shipping price, and those of other weights are combined together to provide the total cost on the shipping solution.

Whether you choose a UPS Shipping solution based on weights or a solution like this is based on your business needs.
