Experiment one worked fine - I did an Instacart delivery from Gelson's - four-day turnaround, but it arrived this morning (for some reason I thought it was tomorrow - had I remembered I would have gone right then since there's frozen stuff - but it all seems fine).  They do replace if they can't find the exact item, but the replacements were all fine by me.  So, I have a few frozen dinners now, and a few other small items.  It's an option should you have Instacart in your neighborhood.  Tomorrow's will be more interesting.
