1. Lower friction because more stores offer free/cheap delivery with decent CX (maybe also wider SNAP acceptance?)
2. Higher opportunity cost for low-income shoppers because of labor market gains (maybe also higher gas prices?)
3. Lingering wariness of high-touch public spaces (not sure about this one, but I still see masks here in Seattle)
The pandemic created a big pull-forward in this demand, but it wouldn't surprise me to see the trend continue.
My general observation is that not as much changed because of the pandemic as people thought would happen. But grocery delivery is something that does seem to have had gains. (Not sure about food delivery outside of the sort of deliveries that have long existed. And meal kits never really took off even during the pandemic.)
