Thrust Vector Wholesale review for Intuitive Shipping

After working with Intuitive Shipping for a few years, I can say that it is the most flexible, most capable shipping cost calculation app currently available. Once everything is set up correctly, the calculations work very reliably. As with everything in life, there are some areas that could still be improved. For example, ZIP code brackets for various US states would be helpful for the initial set up. These must currently all be defined by hand, which can be tedious. The rule definition itself can also be complicated but Intuitive Shipping's support is top notch so figuring things out still works reasonably quickly. It would also be helpful to be able to sync or copy shipping rules across different shops. This is currently not possible and makes setting up more than one shop labor intensive. Last but not least, the plugin is pricey.
