The previous shipping options are limited to one system only. One price for all products per shop.
To create a marketplace for different stores with different products, you need different shipping options.
It would make sense to assign different shipping options to the products themselves. Domestic shipping costs € 2, shipping abroad costs € 5. In order to send products abroad, it makes sense to enter countries in the manual product that the customer can select with the respective prices. Specific countries that the seller can enter manually.
Some products are larger or heavier and shipping costs more than small packages.
Shipping country is Germany: Shipping within the country costs € 2 to Austria € 5, to Italy € 15 for standard products, products that are more expensive to ship therefore require more expensive shipping.
Based on the selected countries and products, the shipping is calculated from the entire purchase, the expensive shipping should then only be calculated not all together.
