This was a survivalist meme a few years ago. Bosnian guy posted something about his experience during the Siege of Sarajevo, and one of his points was essentially "you need more buckets." Like, lots of buckets. Food storage, food preservation, cooking, water storage (drinking, washing, utility), and sewage. And in most cases you won't want a lot of overlap with those; your poop bucket stays a poop bucket. Also jars, bottles, sacks, bags, wraps, blankets, etc. Unsexy stuff, but often critical.
