I have three carriers people can choose from right now:
. 1. USPS standard shipping (the cheapest but longest)
. 2. USPS expedited shipping (more expensive and faster than standard)
. 3. USPS priority shipping (really expensive but fastest deliveries)
I offer free shipping for orders over $99. Right now, when people order for that amount or more, they will see that all 3 shipping methods are free. However, what I want is just to have #1 (USPS standard shipping) free, but display the normal prices for option #2 and #3 because it is not profitable for me to offer #2 and #3 shipping methods for free.
I believe Prestashop doesn’t include that configuration natively.
Please make sure checkout page works after this coding and payment as well, along with any other pages that might be affected from this project.
