1. I have setup shipping for vendors, delivery $10 also can use for free shipping.
2. So, all vendor products have $10 shipping charge.
3. Vendor can tick free shipping on product -> shipping properties and product has free shipping charge.
And now I want to understand how works when you add price in product -> shipping properties -> shipping freight.
I thought if I will add in shipping freight price let's say $5 it overwrite $10 shipping charge and delivery would be $5. But it doesn't work like this. It adding to $10 and the total delivery charge is $15. If I adding negative -5, the price is $5. But I believe this is incorrect way.
Please can someone explain how it works and correct setup as I didn't find any info about it.
