Great app! I was able to configure many different shipping rates to different regions/zones using filter logic.

I can't be more grateful enough for this app exists and is it essential for a small business like mine able to set up rates on different products, Shopify default has all the great features but the execution is poor, with this app you can do much much more and beyond limits. It took a while to understand, as shipping is very complex on Shopify but a lot of limitations and difficult to set up properly.. I especially plan on shipping internationally.. the interface on this app is simple yet powerful, and thank you for the one who developed this app and I hope it can stay free for a small business like us. and Shopify should be included as default features. it is essential for all type of business sells products


for a small store such as mine, this App is pretty useful in targeting customers with different price options for shipping. and the customer support is top-notch. highly recommended.
