In my webshop I have:

free shipping for Portugal
courier shipping for Portugal
flat rate for all other countries
No I want to add a new category of products that will have specific shipping costs:

free shipping for Portugal
flat rate for all other countries

I want this category to NOT have the courier shipping for Portugal
How can I do this? I tried to install the "flat rate shipping based on uk/eu and row and product category" module but it didn't work...

Any help?
