Asda was the cheapest supermarket in June 2019, with a basket of 69 popular branded goods costing £136.27. Waitrose (£158.06) was a hefty £21.79 more expensive for the same basket of groceries.
May’s cheapest supermarket, Sainsbury’s, dropped to second place for June, with its groceries totaling £137.23. Morrisons (£141.98) and Tesco (£145.04) were the third and fourth cheapest supermarkets for the month, respectively.
Online-only Ocado (£153.14) was the second-most expensive supermarket, but buying the same basket of goods would still save you £5 compared with Waitrose.
Shopping at Asda or Sainsbury’s rather than Waitrose would mean that you could buy a bottle of Best Buy gin with the difference, and still have change left over.
How we compare supermarkets

We check prices at each of:
Using data from the independent shopping website MySupermarket, we calculate the average price (including discounts, but not multibuys) for each item throughout the month. We add up the individual averages to get the monthly cost of the identical basket at each store. Head to our supermarket price comparison to see our pricing data for previous months and years.
