I am elderly and usually your delivery drivers leave shopping on porch, more recently in bags left out for them. Twice had the same delivery driver who refuses to put shopping into bags and requests I unload Sainsbury’s containers and pack it into bags myself. Last time, feeling dizzy and off balance, I was unable to cope with it and it was a big order. He took my order away and didn’t leave it. Hoping Sainsbury’s will promptly refund my card payment. It does clearly say on their website the delivery driver will leave the order if bags are provided but this is not true of all drivers, so if you are infirm, heavily pregnant or tired, use Amazon Prime Now with Morrison’s. They deliver in nice clean strong paper bags, email when it is coming, and leave on step and knock the door. They usually wear a mask too. You also get same day delivery and it is free. It is very easy to speak to them, they phone you back if you leave a message online and sort out any problems quickly.
