Hi,
The data is loaded but there is no option to display it. So yes, you'll have to edit show_block_cart.php to display it.
Normally, you should be able to find the discount information in $product->discount there. Also, in the price of the price, you have discount amounts.
For example:
Code:
$product->prices[0]->discount_flat_amount
or
Code:
$product->prices[0]->discount_percent_amount
or
Code:
$product->prices[0]->price_value_without_discount_with_tax
It depends what you want to display exactly.
