As far as food goes, it is not hard to just keep some of what you already buy, and rotate it. One of our big things is rice. We eat it with every meal, so we keep a 100 pound bag in the pantry, and a couple more in the vault. When we empty the one in the kitchen, we pull one from the vault, and next time we get to town, buy another one for the vault. Most of our canned and dried stuff rotates through the vault. Every time we run out of something from the pantry, we replenish from the vault, and write the items on our shopping list. It just becomes part of the routine.
