It sounds like a great idea, but who knows if they’ve either got the flu or this and they start doing this, and a few days later they start feeling off. All those folks the past week got exposed then.
If anyone does this, the best way is to leave the groceries on the doorstep, and have the folks like leave payment either through paypal, or put it in the mailbox or in betwen the storm door and house door when the person is coming over. A No-Contact dropoff is the safest.
I thought that it’s illegal for anyone but P.O. employees to deposit anything in a mailbox.
Maybe a good way is to go through local churches.
They can set up a hotline, and the congregation (and community) can answer the needs list.
