To do this enter the order ID of the order to be changed and press the Edit Order button. On the next page, select if you want to delete a whole item or only decrease quantity. After you submit your request, your buyer or seller in that order will have an option to approve or deny that request.

If the store has a minimum order amount, you do not need to reach that amount again to add to your original order. Simply add the items to your cart and the order will be added as a new batch to the original order at checkout. After order additions, the order status will change to Updated.
