I need to set up shipping costs like this:
A. some items are shipped based on weight and customer’s zip code
B. some items are shipped based on dimensions and weight and these apply to the whole country

Now I created for the A items the zip code shipping zones (about 20 zones) and into them I created the methods (3).

Now for B items I added a zone for the whole country and there the methods. But these methods just don’t show up. And because B items don’t match A’s requirements, nothing is shown.
Also if I move the B zone to top, A shipping doesn’t work either.

Is it possible to define shipping like this or have I defined something wrong? Thanks in advance!
