My wife is also immunocompromised, and we live in the middle of nowhere, where instacart and uber eats and all the other gig economy services don't operate.

We were able to hire our housekeeper to do grocery shopping for us.

Housekeepers; Pet sitters; more generally, there's a lot of people out of work right now, connect with them and you'll find someone who will help with your shopping.

That's a very interesting idea, thank you!
