Sale Price! app for iPhone and iPad

This application will help the user calculate sale prices on individual items by allowing the user to enter the original price, percent discount, and optionally an additional "out-the-door" discount (a discount applied AFTER the original discount has been calculated).

Settings include the option to enable/disable sound, use the "Additional Savings" field, use small or large sets of picker values for percent savings, or even opt to use a keypad to enter percent savings instead of the pickers.

Tax rates can also be applied (as an option in the Settings), so you know what the final price will be. Also, you can enter the tax rate specific to your area.
