keep in mind X being missing from the shelves doesn't necessarily imply that X is being disproportionately purchased by customers. it can also imply that X is relatively harder to restock. the supply chain can maintain much deeper buffers of canned goods without risking spoilage.
the water is probably panic buying, but the other missing items in your list could just be the result of an above average number of shoppers buying a typical distribution of items. also, you don't consider frozen pizza a non-perishable?
the store I go to seems to have recovered from the initial shock. everything seems to be stocked except sanitizer, which is short everywhere. the only other thing empty is the fresh meat display, which I assume is one of the harder things to restock.
