The same drink in the same pack at every supermarket we found it at, cheapest first. Each listing shows that supermarket's own product name, so you can check it is the pack you want before you buy.
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.
When more than one supermarket sells the same drink in the same pack, open it to see every price together, cheapest first. We only treat two listings as the same when the name, the pack size and, where the listing says, the can or bottle all match, so a four-pack of cans is never compared with a four-pack of bottles.
Every “Check at” button goes straight to the supermarket's own page, where the live price is the one that counts. We don't earn anything from those links, and no supermarket pays to be listed or to appear higher up.
