How, oh how, is getting in the queue before 6, waiting ages in the queue, and then finding you can't check out, or if you can, there may well be substitutions or items missing at the last minute when delivered, more convenient than going to the supermarket in person??? Fine if you physically can't get there but I'm making my list (and checking it twice) and driving to Tesco (or Sainsburys, or Morrisons) in person......
