The OP on that thread was ripped apart so viciously that she de-registered.
Tesco have a number you can call to be added to their priority deliveries if you’re vulnerable and I attempted to DM it to her but couldn’t so contacted HQ to ask if they could pass it on and she had de-regg’ed by then.
I actually think that Tesco are the best out of all the supermarkets. Sainsburys won’t allow you to book a slot at all if you’re not on the government list, and the government list itself is a farce because people who shouldn’t be on it are and are now getting phone calls from their GP’s to say they were added accidentally, and people who should be on it can’t get registered.
There has to be a cut-off somewhere and for the most part 80 items should be enough if you e.g. buy in bigger packs so a 3 kg pack of pasta, bigger packs of meat etc.
Also if you’re shopping for others then you need to make it clear that there has to be a limit.
I texted my eXH yesterday to see if they needed anything as I have a delivery slot booked but I emphasised that as there is an 80 item limit. He had had a delivery recently so didn’t need anything.
I would say that if you’re shopping for elderly parents you should get them to ring Tesco and be added to their priority list. You don’t have to be on the government database to do that. That way you can get your full shop and they can get a delivery in their own right.
Iceland are another one who have fairly regular slots available, also for vulnerable people which you have to tick a box for, and Ocado apparently have next day slots available after 6 PM, although I appreciate that Ocado are expensive.
