Change the code: Code: $coupon->discount_flat_amount += ($coupon->discount_percent_amount * $product->prices[0]->$price) / 100; to: Code: $coupon->discount_flat_amount += ($coupon->discount_percent_amount * $product->prices[0]->$price_without_discount) / 100; (several places) in the file administrator/components/com_hikashop/classes/discount.php and it should calculate based on the initial price and not the discounted price.
