No. The estimated shipping cost shown at checkout on the public page is for reference only and will not be written into the PI; the total amount on the PI does not include this shipping cost. Additional fees on the PI come from "Order Amount Adjustment" in Trading Condition Setting, or the seller can manually add them later using "Additional Charges" in the PI details. For sellers who have enabled "Online Direct Order and Shipping", after receiving a visitor's order, please handle the actual shipping cost you want to charge on the PI, then ask the customer to pay or use "Get Payment Link" to send the payment URL to them. Estimating shipping cost requires the product to have weight filled in: filling only weight without dimensions can estimate, but may underestimate; if weight is missing, it will return "Shipping to be determined".
