Start with the same unit
Look for the price per kilogram, litre, item or wash. Compare kilograms with kilograms and litres with litres. A lower pack price can hide a smaller pack.
- For meat, fruit and vegetables, compare the price per kg.
- For milk and drinks, compare the price per litre.
- For laundry, compare the price per wash as well as the recommended dose.
A simple comparison
Imagine a 500 g pack costs £2 and a 750 g pack costs £2.70. The smaller pack is £4 per kg; the larger pack is £3.60 per kg. The larger pack has the lower unit price, provided you will use it all. These are illustrative prices.
Check what is actually included
Products with similar names can differ in quality, ingredients and preparation. Boneless meat, bone-in meat and a prepared meal are different purchases. Read the full description and pack size before choosing.
Check the conditions
A loyalty price may require a Clubcard or Nectar card. Multibuy offers may need more items than you planned to buy. Use the retailer link to confirm the offer and the final price.
