            // Calculate discount per unit
            $discount_unit = $sp['discount_amount'] / $sp['product']['count'];

            // Get final product cost minus discount equal to discount per unit,
            // regardless of product count in cart
            $sp['price'] = (float) ($sp['price'] + ($sp['discount_amount'] - $discount_unit));
          }
