Sainsbury’s triumphed in our annual competition to find the retailer with the best availability.

On the basis of who could most consistently deliver a full weekly shop, Sainsbury’s showed huge a improvement over the past 12 months: our mystery shoppers checked out with full baskets 10 times at Sainsbury’s – well up on last year’s three. It also picked up the most availability wins this year with 26, another massive improvement of 12.
