A fast and easy to use discount calculator! It allows you to calculate the sale price of an item, and the amount of money you will save. Just enter the price of the item, discount percentage, and select the state for that state's sales tax, or just enter the sales tax. The sales tax will be saved after you enter it the first time, so you do not have to re-enter it each time. However, you can change the sales tax at any time. The amount you will save and the total you will pay are displayed. Features a large, easy to use keypad, and an easy to read display.
