Compare Prices helps you compare the price per unit of up to 6 items at the same time, in order to help you save money by making smarter shopping decisions at the supermarket.
It also helps you compare prices between items even if they are not in the same measurement units, for example between imperial and international units.
It's really easy to use, just pick two or more items that you are interested in buying, add into the lines the price and measurement units of each item.
Highlighted in green you will be show the items that you should buy, since their price per unit is the lowest. If two or more appear highlighter in green, that just means they are the exact same price per unit, so you can pick whichever you prefer in that case.
