Multi Origin Shipping - How do you fetch only one shipping price?

You can of course cry like a baby and hope Shopify will covert your store to a single origin store, and use e.g. Zapiet for pickup at store - in many cases that is a much better solution than refunding shipping costs, @arayard .
It’s kind of a solution, as long as you’re aware of the shipping profile/shipping functions you give up changing to single origin.
