Helping with groceries - the money side

[Groceryhelper]

I want to help any elderly neighbours etc who are going to be isolated, with help with shopping etc. Given if they could use the internet, they could probably just order food themselves and not need my help, I'm going to assume anyone I help won't be able to transfer money electronically.

How can I help them? They won't be able to safely leave their houses to withdraw cash and I wouldn't want them to put themselves at risk like that

But I can't afford to buy their shopping for months on end, and if they have funds (pensions etc won't be affected) then it makes sense for them to be able to pay for it.

Any ideas?

Most elderly people I know still have a cheque book, could that work?

I just posted similar to this on another thread. I've been branded a heartless cow for bringing up the money situation when arranging to help out an elderly neighbour. I'll happy go to the shops and pick up his essentials but I cannot pay for this and the way I see it is that he would have had these outgoing costs anyway. I've suggested that if he can't get money to me on a regular basis then I could pay for his stuff on credit card and have him reimburse me in a lump sum when this is over. There's an obvious risk with this option though which I don't really want to say...
