I have 2 categories of product. For one of the categories (irregular sized item), I would like to set a shipping rule that gives the customer only one option for shipping. And when the customer orders and item from both categories, they will only be able to choose the shipping for the irregular sized item category.
I have tried to create a custom shipping rate, but then the rates stack and the customer is essentially charged shipping twice. I thought that I could just use weight and then it would only use that shipping option which applies to weight for the item which has a weight value entered, but that doesn't work either.
Has anyone encountered this issue and maybe has a fix?
If what I'm trying to describe isn't clear, please let me know and I'll do my best to clarify.
