I think my post got a bit lost. I wasn’t offering a solution to Costco but I have thought of a solution to the shopping problem. This isn’t necessarily about reducing your risk to others but actually reducing your experience of risk. With your condition, ending up on a ventilator or on oxygen in hospital for weeks will be truly horrific.
Do you have a Sainsbury’s near you? They don’t have a minimum on click and collect - they charge £4 instead. (But what is £4 versus sparing you ending up on a ventilator?)

Tesco have reduced their minimum click and collect to £25 www.tesco.com/groceries/en-GB/zone/reasons-to-shop
If you put in one expensive thing, like meat, cheese or branded washing tabs, or some expensive nuts like pine nuts, you could easily make £25 without having too much to carry. Could you get/ do you have a shopping trolley?
You can’t eliminate all risk as I know you have to go to work and use public transport, but shops are the most dangerous places apart from schools, so you would eliminate a major risk factor.
Here is my other suggestion if there is no Tesco or Sainsbury’s near you, as it looks like you need to anticipate the mask mandate tightening up and prebook delivery slots now! Book them for weeks away if that is all they offer.
You could even get a cheap freezer second hand delivered, or a new one that curry’s or similar will carry in and install see this: business.currys.co.uk/catalogue/kitchen-domestic-appliances/refrigeration/chest-freezers/essentials-c95cfw20-chest-freezer-white/B287106B?cidp=Froogle&gclid=CjwKCAiAz4b_BRBbEiwA5XlVViNBO2KvD2OCtliCgQGRFxkRmkB-e0pDTEpjA7WiBnTNb7togQ9-txoCyw8QAvD_BwE&gclsrc=aw.ds
You might not have room for it, but it can sit in a living room or wherever as it will be a temporary solution. Jan sales will have some massive bargains too
You can then book a delivery slot in 4-8 weeks’ time and put loads onto it. You can then immediately book another delivery for next available slot 4-8 weeks after THAT - and not have to worry about this (nor put yourself and others at risk) again.
