Move Discount field below Shipping field in Orders Details

  ajax, email, php, woocommerce, wordpress

I would like to move the "Discount:" field below the Shipping field in Order details. I also want this to reflect in woocommerce emails as well.

Please see the attached image for better understanding.

I tried to find the file in the woocommerce plugin to make the changes, but there were so many entries as Discount, it totally confused me. Any help would be appreciated. Hopefully a child theme solution would be a blessing. Thanks in advance.
