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 Morrisons, Tesco, and Asda.

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 all major UK retailers. 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
- Protein supplements: price per gram of actual protein — not per serving, not per 100g of powder
- SIM-only: price per GB of data — stripping out introductory discounts and contract lengths
- Nappies: price per nappy by size — because a “bigger box” isn’t always better value
