Every beer and cider we found listed online at Sainsbury's, cheapest per litre first: the shelf price, any 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 range at Sainsbury's about once a day and list every drink we find. Where Sainsbury's shows a Nectar price, the listing shows it beside the shelf price, and ticking Nectar uses it in the list and the sorting. Offers that need a Nectar card say so.
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 is independent of every supermarket: we earn nothing from these links, and nobody pays to be listed or to appear higher up.
