Re: For furniture...
"One of the problems we over-70s have is that the supermarkets themselves are high risk areas, and around here none of them have stock of anything in the way of cleaning products."
You might be surprised by what good you can find in the smaller convenience shops, especially local independents and, if you still have them in your area, local butchers and bakers. The majority use only large supermarkets these days and in large busy shops there's a crowd psychology effect that encourages panic buying. Likewise pound shops, places like B&M, Home Bargains etc.
