But next thing… Do you have any tips to next problem. If product costs 10 dollars and shipping 10 dollars, i want take seller percentage from total, not only from product price. With my 10% percentage, i get only 1 dollar, not 2 dollar.
Actually percentage on the shipping total is illogical for that we do not have this system in our plugin. But if you want to set percentage on the shipping cost then little more of modify will require for your plugin.
