The mainstream UK grocers have been tripping themselves up all year and everyone has been laying into them while they’re down.

Yet online grocery is marked out as the rare success story, but we’ve been at this for a while, so set it in its context: why haven’t those out-of-town sheds gone the same way as the bookstores? Why are people still shopping there when you consider the traffic, parking, weather, other people, limitations on what you can fit in the car, and everything else you’d rather be doing? Something must be wrong somewhere. Why don’t I do my grocery shopping online? I must be target group 1. But they’ve never asked me why I don’t.
