# Unit price comparison calculator

Converts each pack's price to a common unit price after its shelf offer, ranks the packs, and shows the spread against the best deal.

Enter a pack size and a price to start comparing.

Offers apply the way a till applies them, on the numbers you read off the shelf label: percent off cuts the pack price, a buy N for M averages across the packs you must buy, and buy one get one free halves the pack price only because you take two. Weight never competes with volume here, since no honest price per kilo exists for a litre of anything. The tool is not connected to any shop database, so every price, size and offer comes from what you type; check the small print on shelf-edge labels for exclusions.
