Unit Price Comparison
Compare products by price per unit to find which is genuinely better value.
Cutting through package sizes
Shops make value hard to judge by selling the same thing in different pack sizes at different prices, so the cheaper-looking item is often not the better deal. This works out the price per unit — per litre, per hundred grams, per item — so you can compare products on the same basis and see which genuinely costs less.

The bigger pack isn't always cheaper
The common assumption that buying bigger is always cheaper per unit is frequently wrong — retailers know shoppers believe it, so the large size is sometimes priced worse per unit than the medium, and multi-buys are not always the saving they appear. Comparing on price per unit is the only reliable way to see through this. Shelf labels often show a unit price to help, but they are not always consistent in the units they use, so working it out yourself settles it.
Common questions
Is the bigger pack always better value?
No — retailers sometimes price the large size worse per unit, banking on shoppers assuming bigger is cheaper. Only price per unit reveals the truth.
How does comparing per unit help?
It puts differently-sized packages on the same basis — per litre or per hundred grams — so you can see which genuinely costs less.
