My grocery store experience.
I tried to place an online order through Walmart.com last weekend. Said I'd have to wait until Tuesday.. No big deal I figured. By Sunday night I got an email saying they couldn't fulfill my order. My wife had some ad-hoc luck at Aldi to get a few things. But based on the continued rumors that Illinois is due any day to go in shelter in place, I make the trip out to Walmart last night. We don't normally shop there but it's so much larger than our Jewel I figured I'd have better luck.
It was definitely hit or miss. Tons of produce gone, but a healthy supply of bagged apples, for example.
Fresh meat was in very short supply, but they had ground Italian sausage which is great for chili or meat sauce. Lots of frozen meat, but some of it was weird. I picked up a bag of goat for instance. Never had goat, but it had a Mediterranean bowl recipe on the back that sounded good. Covid-19 inspired dining here I come!
The shelf stable stuff was okay except for a few thing a like rice, but even that I managed to find two boxes almost hidden on a lower shelf. Lots of things like nuts and dried fruits.
Then there were just the other oddiities. All the cheap frozen pizza cleared out but plenty of Home Run Inn and some Digorno. Decent amount of spreadable butter but very few butter sticks except for this expensive "European style". And my wife wanted to do some baking while we're holed up. So she's gonna bake with fancy butter I guess.
Overall I think you just gotta go in with a flexible attitude. Certainly was not going to walk out of there feeling like I couldn't feed my family, and I definitely over-bought but tried not to clear out stuff completely. I'd have much preferred if online ordering had worked to limit my public exposure, but if this drags on I think I need to just order all the non-perishables through Amazon Prime Pantry and make quick trips to the grocery store for produce (stocked up on a decent amount of frozen meat now)
