Discount 

There are several methods to get a discount.

1. Use the discount field for a front end user and enter the percent of discount.
2. Use the price2 field for special front end user groups or other things. This setting is done in TypoScript via the IF-statement.
3. Use the discountprice calculation where the discount depends on the value of the total number of the products which have a special price. This will be available for the front end user group discountGroupName.
