If you wish to place the similar or identical order to the one you have already submitted, there is a way to avoid a long product selection process and just copy the items from the original order.
The Re-Order option triggers a new checkout using the items from an existing order.
To proceed with re-ordering:
Navigate to Orders in the Quick Access Menu, or click Account and then click Order History in the menu on the left.
Select the order which you want to re-order from the All Past Orders section. The section contains a list of all the orders submitted previously.
Click Re-Order on the right to open the Checkout page.
Alternatively, click View to check the details of the selected order, and then click Re-Order directly from its view page.
