Why it can help
Different pack sizes and promotions can make the shelf price misleading. Unit pricing gives a more consistent comparison.
How to try it
Compare similar products using the same unit, then consider whether you will actually use the larger pack before it spoils.
Things to consider
The lowest unit price is not automatically best if the product will be wasted or you cannot comfortably afford the larger upfront cost.
