I happened to wander into a Tesco Extra (their biggest size of store) this afternoon. The shop [1] has grown in size considerably since I last used it a long while back. I have to say that I am more convinced than ever that Tescos are planning to put just about everyone out of business. The range of stuff was quite amazing and I got suckered in just as much as the next person. Even though I was only really there for some food shopping I ended up buying some non food items as well and spent far more than I expected. I could quite happily have spent a load more money on other things too. The thing that was particularly obvious was how well they obviously know their customers. The range of food and ingredients was very specifically tailored to reflect the ethnic mix of shoppers with goods that you would not normally get in a standard supermarket. It's no wonder they are doing so well if it is all so well planned and researched. So should we be scared of Tescos and their dominance or should we be happy that they exist? If the former what could practically be done to get them under control? [1] Lea Valley - which darsy will know.
