We have our groceries delivered every week (sometimes semi-weekly), and have done since 2018 or so. The people who pick the order work for the store, the people who deliver are gig workers.

The only "selection" complaint I regularly have had is the bananas are nearly always very unripe - like several days from being edible. But then I went to the store myself for several weeks and realized they just never have ripe bananas.

In other words, they're doing as well as I could do if I were shopping it myself.
