        $db->setQuery('SELECT SUM(shipping_discount) FROM #__awocoupon_history WHERE estore="redshop" AND order_id='.$order_id.' GROUP BY order_id');

        $shipping_discount = (float)$db->loadResult();

The variable {shipping_total_including_discount} now contains the shipping total including vat, with the discount included. You will then have to update your templates and emails to use the correct dynamic variable.

Some of the templates that need updating include:
- cart/cart
- checkout/checkout template
- order_detail/order detail
- order_receipt/order receipt

For email, you should update order mail.
