Which Price makes price comparison simple, particularly when stores go out of their way to use different units of measure for the same type of item. Just enter the price and number of units for each item, and use the scroll wheel to pick the unit of measure. The best price is highlighted in green. How far the needle moves in the meter indicates how much better the price is.INTUITIVE UNIT CONVERSIONWhen you choose units to compare, Which Price is smart enough to know whether or not the units can convert from one to the other. The scroll wheels will automatically move to the correct section, based on what you choose.DO ONE THING, WELLWhich Price does not try to do anything but be the most intuitive price comparison tool possible.
