I will be 86 Next month Can I order groceries, pick them up outside the store so that I will have very little contact with people?.

You can order on instacart and even have it brought to your home but I don't think you can order and have it ready they don't keep bags so I think they wouldn't be able to provide a service like that

Not at this location. Sam's, and Walmart offer this and perhaps delivery depending upon location.

I don't think they offer that yet, Walmart next door does.
