To pay for multiple orders at once, you can go to "My Account" and check all the orders marked as "Unpaid". After you click on the unpaid order's order number, you will be able to see all the detail information of unpaid orders listed. You can then select the orders you want to pay. The total will automatically be added up. After pressing the "Proceed to pay" button, you will be led to complete the rest payment process.
