Advanced Shipping Rules

When I created my "store" (awhile ago), the web designer I hired selected this app and set it up for me. It's been working great and I have no problems with it. I wanted to make a small change, but since I am not technical I had no idea how to do it so I reached out to customer service and they were extremely prompt in replying. They then, quickly and cheerfully, helped me make the adjustments I needed to in regards to my shipping. Thank you!!
