Our local store, QFC in Seattle, has been doing a great job of selecting produce for our curbside delivery. Quality has matched or beaten what I normally select myself.

I don't know where they're finding such huge broccoli crowns, but they're consistently doing so (we're ordering per crown, and paying per-pound, so the incentives are aligned there).

On substitutions -- they require customer review of every substitution.

(We take the errors in stride -- a global pandemic is a time that we can be glad to have such reliable high-quality food at all. The best fail was the day that Anjou pears got substituted in for garlic, but somebody found the garlic, so we got garlic too :).)
