Loyalty Points calculation is not based on actual payment ?

[wooxudong]

The business rule is stating that loyalty points calculation are based on amount spent on the product.

   if (product.getProductCode().startsWith("DIS_10")) {
                discount = (product.getPrice() * 0.1);
                loyaltyPointsEarned += (product.getPrice() / 10);
            } else if (product.getProductCode().startsWith("DIS_15")) {
                discount = (product.getPrice() * 0.15);
                loyaltyPointsEarned += (product.getPrice() / 15);
            } else {
                loyaltyPointsEarned += (product.getPrice() / 5);
            }

The code that is calculating the loyalty points does not deduct the discounts and based on the original price. Is this expected?
