From the Commissioner: Grocery shopping hack to make your dollar go further
One simple way help you save money and get bang for your buck when grocery shopping is to use unit pricing. It doesn’t just show you what a product costs, it shows you the price per standard unit of measurement, such as per 100g, per kilogram or per litre. This makes it much easier to compare value across different brands, package sizes, specials, and even between packaged and unpackaged or fresh and frozen products.
