Thank you.
I am hoping to gain some independence back, when I feel up to it.
I will be able to get a taxi when I need to go somewhere.
I can shop online, without worrying that it costs more.
I can eat the food I have been advised to, to help my liver, too.
I can pay the people who have been looking after my grandson.
I can even buy a hat to cover my bald patches!
In my experience, shopping online does not cost more, at least not from Tesco, in fact, for me it costs less, in recent years much less.
I get my grocery delivered by Tesco.
Each delivery is notionally £4.50.
However, I have a Delivery Saver Plan. That costs me, notionally, £72 per year, though looking just now it has gone up to just under £84. But there are 6 month plans.

However, I don't actually pay all that, because if you have a free Tesco clubcard, you get a point for each pound spent. And the points redeem at a face value of one penny each, YET there are some triple value offers and one is for paying for the Delivery Saver Plan. So for renewals in recent years I have paid £24 in Clubcard vouchers, so no money actually leaving my bank account to renew the plan.

Each order must be £40 or more when ordered, but if they have not got something or a substitute is cheaper and the bill is less than £40 then the small basket charge of £4 is not charged as it is the value when checked out not what is actually delivered that counts.
If the substitute costs more then they charge you the price of what you ordered, not the price of what you got delivered.
The Tesco system is very flexible, you can opt for substitution or not on an item type by item type basis and you can add a note to the personal shopper for each type of item.
You can even specify type of substitute and include NOT too.
So, example,
if sub, vanilla or dark choc please NOT caramel
when ordering chocolate soya dessert
or
Please send some green and some yellow if poss
when ordering bananas
Cramming information into the 55 characters is an art form. 
These days, and for some years before COVID-19 too, so not because of that, if I did not get home delivery I would need to be paying Age UK or similar to do my shopping for me at quite a lot per hour.
I don't know much about other supermarkets though I did see somewhere that one of them always substitutes, no option to put don't substitute and if the substitute costs more then charges that increased price without consultation.
I have known people speculate that if you don't go and choose it yourself you might get poor quality sent. I have not had poor quality delivered. In my experience the personal shoppers do their best to do it well. On the very rare occasions when something has gone wrong, Tesco has always refunded promptly, accepting my word, just phone the free number and speak with someone.
