Hello,
I set up 2 shipping zones,
one of the zip codes is 08221-80226 which is the default delivery area and there is no delivery fee.
The other one is 08227, and the delivery cost is 2 euros
Although I enter 08227 in the postcode field, the system still selects the default area and does not calculate the cost
My idea is to add a js code on the CHECKOUT page. When the user enters the postcode (leave the postcode field), js will update the delivery area of the cart, or the delivery cost
I read the docs of cart, but not sure how I can update the cart on this page
HELP PLEASE!!!
