Every Pale Ale we found at the supermarkets we check, cheapest per litre first: the shelf price, any Clubcard or Nectar price, advertised multibuy offers and the price per litre, with the same pack at other supermarkets a click away.
Prices are each supermarket's default online listing without a delivery address (Aldi's are the in-store prices it publishes, as it doesn't sell beer online), so they may vary by location and delivery method. Minimum unit pricing applies in Scotland and Wales, and multibuy offers are not available in Scotland.
We check the beer and cider ranges at Tesco, Sainsbury's, Asda, Morrisons, Waitrose and Aldi about once a day. A drink is listed here when its name says Pale Ale, or when the name doesn't say and it is the style the drink is known as; where we weren't sure, it isn't here.
Prices are each supermarket's default online listing without a delivery address (Aldi's are the in-store prices it publishes, as it doesn't sell beer online), so a local price or a store shelf can differ. Every “Check at” button goes to the supermarket's own product page. UK Beer Deals earns nothing from these links, and no supermarket pays to be listed or to appear higher up.
