We have a live Magento site that uses WebshopApps MatrixRate for shipping calculations. Rates are flat rates based on Country/Region/State/ZipCode only (no weight calculations). We are having issues with the separate rates for Hawaii, Alaska and Canada not working - Alaska gives same rate as continental U.S. Also the Shipping Estimator provides incorrect information.
I'm sure this is a quick fix, but looking for someone with prior experience using WebshopApps and Magento. Please provide examples of Magento sites developed/worked on.
