Feed the household for one week on $40. Every item shows its unit price โ the real number that decides whether you're getting value. Beat the optimal basket and we'll show you what the savings become.
Unit price is just pack price รท pack size, expressed per 100g or per litre. Australian supermarkets must show it on the shelf label โ it's the small number under the big one, and it's the only honest way to compare a 500g jar against a 1.5kg one.
But bigger isn't automatically cheaper. A bulk pack with a great unit price still wastes money if you don't use it all. The cheapest real basket is the lowest unit price among sizes that match what you actually need โ which is exactly the trade-off this game makes you solve.
Prices here are illustrative and rounded, not scraped from a live store. The arithmetic works anywhere.
Checking what's actually in the cheaper pack is a different question โ FoodLabelReader.com handles that one.
