In our previous woo-commerce store, if someone bought more then 1 of a product, it attempted to estimate how many packages would be needed based what the packages can hold, etc. How do I make sure that if more then 1 is purchased, that we are not losing a money b/c shopify didn’t estimate shipping correctly. Thanks in advance!

Hey @purdypetfood , thanks for your question.
Most of my clients already had their shipping profiles set up before I started working with them so I’ve never dealt with this personally but there should be a bunch of Shopify Apps on the app store that could do this kind of calculation for you.

Here is a list of a bunch of popular Shopify Apps related to shipping: https://apps.shopify.com/search?q=shipping

Take a look at those apps and read the descriptions for each.

I’m sure one of them has the functionality you need but if it doesn’t, feel free to reach out to me and we can figure something out.
