WHICH PACK SIZE IS REALLY THE BEST VALUE?
Price per kilo, litre and piece: compare pack sizes fairly
Pack sizes differ per supermarket and per brand, so the shelf price says little. Mandje converts every price to the same unit, per kilo, per litre or per piece, and marks the best-value size. That works within one store and across supermarkets.

HOW IT WORKS
In three steps
- 1
Find the product
Next to the price of every product sits the price per kilo, litre or piece, at every supermarket.
- 2
Compare sizes and brands
Family pack, own brand or A-brand: the same unit makes them comparable at a glance.
- 3
Pick the best-value size
Mandje marks the cheapest unit price, even when that is at another store.
