I accept that having your shopping delivered is a great convenience for many of you. I have heard of some very strange substitutions, from friends. I live alone, and enjoy my trips to the supermarket, treating them almost as part of my social life. There is always a baby to smile at, or a request to someone taller to reach something down from a top shelf, which usually results in a brief chat. I also make a habit of walking up and down every aisle, just for the extra exercise. It's surprising how many steps that takes in a large supermarket.
I've never felt the need to online shop for food. I just go at quieter times since Covid arrived. Maybe, one day, my elderly legs won't be up to it any more, but not yet.
