I am so happy I found this App. I have some specific shipping rules based on certain products and shipping destinations and this App does the job. And it's FREE! Not only that, their customer support is first class. Philip went above and beyond providing me with much needed assistance with the set-up. Once you get the hang of it, this App is very simple to work with. Highly recommend.


Over the course of years I've installed several shipping apps for customers and not one was this easy to set up. It worked right away after days I tried to get another app to work since it was my customer's choice. Thank you for the great app!
