I have created a form with one product. I added an option to ship it or pick it up (free of charge).
If the customer chooses to ship it, the shipping cost depend on the shipping destination (country) and on the number of products (which determine the weight of course).
I don’t want users to choose a shipping option, because they might select e.g. a national shipping instead of international and pay too little.
How can I achieve this seemingly simple set-up? Thank you!
