It all depends on where in the US one lives. Here in NE Ohio, I can get free curbside pickup at two local grocery stores and a few others charge a small fee. I tried the delivery service once at a different grocery store, but I was dissatisfied. They charged me a fee and they were late, and there were inaccuracies with my order as well. Easier to pickup for free at a different grocery store and I would rather avoid paying the service fee (and my order is correct). I think Milkduds lives in a smaller city and they don't have as much to choose from for now, hopefully things will improve in the future in her area.
I was a stockpiler for a long time before COVID-19 was a thing. I have a chest freezer in the garage that is nearly full with a variety of pork, chicken, beef, fish, prawns, and vegetables, and containers of homemade pasta sauce, chili, and soups. My pantry has lots of pasta and canned goods. I still keep doing my curbside grocery pickups regularly though, as from what I am reading there are possibly going to be disruptions in the food supply chain. Better to stay ahead of it.
