SMART Shipping Rates & Rules

Perfect app that helped me set up my desired freight classes. I had quite an advanced setup with 25 different zones with 8 weightclasses for each zone, the app let me set up all my postal codes with weight. If i could wish for one thing it would be that the app let you have more then 25 zones, i just managed to get all my postal codes inside :) But the app is free, so im happy anyways!
