I live right in the middle of the central belt, we have M&S, Lidl, Tesco, Sainsbury's, Morrison's, Asda, Aldi, Iceland, B&M's, Home Bargains, Farmfoods and the Co-op, all within either five minutes walk or ten minutes drive, from the house. There are three 'corner shops' too within walking distance.
None of the ones I've been in recently (the first four on the list) had any shortages, and I haven't heard anyone mention anything about empty shelves.
Not a lot of special offers/buy one get on half price sort of thing, but nothing missing that I noticed.
The Greengrocers have their usual spread of boxes out too, and the Butchers and Fishmonger's are looking like normal.
