Has anyone had success using Script Editor to change the shipping cost of an order based on the content of the cart?
I want to be able to apply free shipping to an order that contains a certain SKU.
It's currently not possible to modify shipping rates using Shopify Scripts. We're working to improve the offer for Scripts and shipping is definitely something we'll be looking at. Thanks for your input :) If you have more suggestions we'll be sure to look at them too!
