How to code this free shipping rule?
Hello. I'd like to create a shipping that states "buy three of Product A and receive full shipping on the entire order."
So if a customer buys three lip balms, for example, they get free shipping on the full purchase.
I am a coding newb, and not sure how to do this. I already have the two standard USPS shipping rules enables, but not sure how to add this new one.
Thanks!
