Advanced Shipping Rate Manager

This app is great, as it is extremely powerful in setting up rules, rates and shipping methods. It ties into our shipping accounts, and supports all rates, including FedEx One Rate, which isn't supported by everyone. Dan and Bert are also extremely helpful and responsive. They have taken the time to help us set up our stores and make sure that all of our rates are correct and everything is set up accurately. And if we have any issues, they respond immediately.
