Beer — £/litre & £/ABV%
Shelf price is misleading when pack sizes and alcohol content vary. We rank every beer by price per litre and price per unit of alcohol — across Tesco, Asda, Morrisons and Sainsbury’s.
Soft drinks — £/litre
A multipack of cola can cost several times as much per litre as the bottle beside it. We rank colas, energy, squash, juice, water and mixers by price per litre — across the same four supermarkets.
By type: Fizzy & cola Energy drinks Juice & smoothies Water Squash Tonic & mixers
By brand: Coca-Cola Pepsi Diet Coke Fanta Monster Red Bull Lucozade Robinsons Innocent Fever-Tree

The price in a SIM advert is often the price for the first few months. We rank every plan by what it costs across the whole contract, with intro offers, price rises and roaming limits shown next to the price.

When you pick up a pack of beer, you see a shelf price. What you don’t see is whether that price is good value — because the retailer hasn’t done the calculation that would tell you. A 10-pack at £12 might be worse value than an 8-pack at £9. A 4% lager at 80p/can might cost more per unit of alcohol than a 5% one at 90p.
BargainSniper does the maths for every product we track, across the four biggest UK supermarkets. We surface the metric that reveals the true value:
- Beer: price per litre and price per percent ABV — so a strong ale and a session lager are honestly comparable
- Soft drinks: price per litre — so a 24-can multipack, a 2-litre bottle and a single from the chiller are finally the same question
