I also recommend those food-grade 5 gallon buckets as mentioned earlier. You can also brine a turkey or whatever in them, just make sure they are food-grade for that. Not a bad idea to freeze any pastas/grains in advance to help kill any pests before they're put in a sealed bucket and find out one package had cereal moths 6 months later.

While things are much closer to normal through this summer is a good time to restock/stock up. It's easier to already have it than to try to run out and buy ten when the news becomes back-to-back coverage of Sodomy Geese. Most people contribute to the panic buying only because they know they won't be able to access stuff because of the panic buying.
