Good to know
- Many shelf labels in Australia already show a unit price. Check that the labels you compare use the same unit (for example per 100 g, not per kg).
- A lower unit price only means a lower cost per gram, millilitre or item. It doesn't account for how much you will use before it expires.
- For multipacks, enter the size of one pack and the number of packs.
