"It seems Tesco's performing its own supermarket sweep, knocking competition out the way in the process and loading up on market share. As a full-line retailer it maintains an edge over the likes of Lidl and Aldi where you can't quite find some more obscure ingredients. The enormous investment Tesco's put in to being more affordable has also helped retain and attract customers while inflation's been running so hot. Inflation has fallen across the first half as Tesco has been able to normalise some pricing. Of particular note is the success of Tesco Finest. People are saving by treating themselves at home instead of going out and Tesco has been building out its more premium offering. The wait to catch that extra demand is now paying off.
