The small number that makes a big pack easier to judge
A lower pack price is not always better value. Start with the measurement, then check what the price actually buys.
Compare the same measurement
Price per kilogram belongs beside price per kilogram; litres belong beside litres. A price per serving needs a verified serving size. Compears leaves the unit unknown when it cannot establish a reliable basis.
Keep the product differences visible
Concentrated detergent and a ready-to-use cleaner can have very different doses. Dry rice and cooked rice have different water content. A unit-price leader is not a quality recommendation.
Read the offer conditions
A multibuy price may require several packs. Membership prices, delivery fees and minimum basket values can change the total you pay. Check the retailer before checkout.
