Customer adds “product A” to their cart. I need an app that will generate shipping costs based on that customer’s selected item’s box size. If someone adds two “product A” to their cart, I need it to charge shipping twice, because they will be shipped separately.
I do not need boxify because I only have 2 box sizes I need. I do not need Advanced Shipping Rules because I need the app to generate the shipping cost based on Shopify’s rates, not retail rates.
