List of household/life items that are trivial to buy and store in bulk?

I'm shopping around and noticed that all kinds of soaps and toothpaste store indefinitely and are relatively compact, compared with, say, paper towels and toilet paper that take up a tremendous amount of room. Are there any other items that scale really well in price and are easily stored like soap that are frugal to bulk buy, besides food?

I've been trying to spend less time in the drugstore and more time living my life.
