In Notifications, sended to users after successfull checkout, we can display product prices with discount.

Let's see notification "Order was placed (Customer)". Go to page

Shop - Marketing - Notifications - Order was placed (Customer)

It is necessary to work between this construction:

{foreach $order.items as $item}
    ... {* Order products output *}        
{/foreach}	

1) Change price of each product. Find construction:

{wa_currency($item.price, $order.currency)}	

Replace it to the following:

{wa_currency($item.price - $item.total_discount/$item.quantity, $order.currency)}	

2) Change total price of each product. Find construction:

{wa_currency($item.price * $item.quantity, $order.currency)}	

Replace it to the following:

{wa_currency($item.price * $item.quantity - $item.total_discount, $order.currency)}
