Advanced Shipping Rate Manager

All I can say is this is some of the best app support I have ever received. Not only did the app do exactly what I needed, but I was guided through with set up over a screen share call (what a treat). I searched all over the app store for the right extension to help us with the issue of combined shipping rates for multi warehouse locations and this is the only app that was capable of doing this. Huge shout out to Burt for the help. He was patient, personable, kind, and extremely knowledgeable about the app and Shopify. Give Burt a raise and pat your developer and founder on the back. I am impressed.
