You can use the discount calculator to calculate the discount and savings for your shopping list items.
Add the items of your shopping list and the discount percentage of each of the items in your shopping list and the discount calculator will show you the final price after the discount and how much did you exactly save.
You can also specify the sales tax percent which is optional and the calculator will add the sales tax to the total cost.
Use your phone menu button to access the 'Discount Calculator' which is one of the many calculators built inside 'Quickey Calculator' then select the discount calculator. You can also tap on the menu key in the upper left corner of the calculator to access the discount calculator.
