I think it depends on where you live.
I am not on the shielded list but prefer not to go to shops as we are both over 70 and OH is asthmatic.
I rarely used Tesco before for shopping, but have got a delivery every week. I have a nectar card for Sainsbury and JL and Waitrose card, but had no chance with them. Managed odd slot with Asda, but am very happy with the quality of food and delivery service from Tesco who have employed many more drivers in this area.
My main shopping used to be with M&S whose only contribution has been the shopping hour for the elderly (very busy) or some food boxes, which weren't any use to us. Not into Percy Pigs
