I made this simple app to use in stores by people when they see a big sale sign behind the windows of shopping centers. People can easily enter the tax amount in their area as well as the current discount value to find the final price. It is a simple calculation but it would be handy to calculate that fast in store when we are purchasing several items with different discount values.

Previous problems in keypad entering and font size in different devices were fixed. This application is so simple but really handy for shopping in stores. When we see a sale sign on the window and enter one store, we need to know the final price of different products fast. We can estimate in our head but accurate prices will help us to select which product is better to buy. There are complicated apps on the market but this one is the simplest one.
