At least at Costco, no shortage of the basics. Some specialty foods are spotty. Have one week, not there a few weeks later. Plenty of decent quality hand sanitizer, wipes are on and off.

Local Safeway supermarket is still short on some canned goods like soups and such. Plenty of TP and Paper Towels, as long as you are not too choosy. OK on disinfecting cleaners. Wipes most of the time. No cookie shortage, very critical.

Ammo in any common caliber not to be found on shelves. Most FFLs hold for their best customers. Can still be found online if you are willing to pay, although perhaps not your preferred brand or model seems to work well for my friends who didn't stock up or have purchased their first firearm.
