How to use unit pricing at Australian supermarkets

Why unit pricing matters

The headline price on a pack does not tell you which product is better value. Unit pricing shows cost per standard measure (for example per 100g or per 100ml), so you can compare different pack sizes and brands on a level playing field.

Australian supermarkets usually display unit pricing on shelf labels and online listings. Regulations require consistent presentation in many cases, but small differences in how similar products are labelled can still trip you up.

Practical tips

Check that the unit matches what you care about—for pantry staples, per 100g is common; for drinks, per litre is clearer than per 100ml.

Watch for multi-packs and promotional bundles: the unit price should reflect the total contents, but it is worth sanity-checking against the receipt.

Use TrolleyChecker search when you already know the product name—unit pricing is great in-store, while a price comparison tool helps when you want to see multiple retailers side by side.

Search for staples such as milk, rice or olive oil on the browse page, then filter by store and category to line up comparable packs before you shop.
