Hi,
I believe this is a great idea. In fact, it's been years that this is already available by default with HikaShop.
You need to activate the "shipping price per product" setting of your shipping methods.
And then, when you edit a product, you'll see a "shipping prices" area where you'll see a list of all the shipping methods with that setting activated.
Then, if you click on the "+" button for a shipping method, you'll be able to enter additional fees for the product for that shipping method, or check the "block" checkbox to discard the shipping method when this product is in the cart.
We actually have a tutorial about it here:
www.hikashop.com/support/documentation/3...ng-manual-price.html
This is mainly used for two things:
- set shipping prices per product
- forbid the sale of some products to some areas (for example, forbid the sale of guns outside your own country)
