I'm sorry but I don't understand it.
This is de situation at this moment. I have only category A products:
- Order amount between 0,00 and 25,00, shipping costs are 11,50
- Order amount between 25,00 and 75,00 shipping costs are 6,75
- Order amount from 75,00, shipping costs are free
I have three shipping methods, so the shipping costs are calculated automatically.
For category B products, it should be:
- Order amount between 0,00 and 35,00, shipping costs are 4,50
- Order amount from 35,00, shipping costs are free.
So also here, the shipping costs should be calculated automatically.
For example: when someone buys both category A and B products, it is possible that he have to pay twice the shipping costs, depending on the order amount of the category A and B products.
I hope you understand what I mean and I really hope that this is possible.
