You don’t cook with fresh produce, do you? No way I could go shopping every 4-6 weeks.
Oh no, the people of olden days starved to death for lack of fresh produce! Of course, I cook with fresh produce. You just have to know which lasts for many weeks and which needs to be eaten quickly. Squashes, onions, potatoes, cabbage, carrots, apples, citrus, pears, etc. can last past the previous shopping trip. If the bombs start falling, take note.
