I tested almost every single app on the Appstore to find a solution. Please read this and let me save you some time and headache. If you are like me and Shopify’s shipping settings don’t fit your business’s needs, I HIGHLY RECOMMEND downloading Shipping Rates by Smartive
Great customer service and the functionality is amazing. This app will let you accomplish anything you are looking to configure. This app absolutely saved us so much time and headache, giving us the freedom and the power to setup our unique shipping rates as we needed.
