Just to add, really poor people can't afford to shop for sales. Right now, I have all kinds of stuff that will never go bad and I can use eventually, that I bought on sale (paper goods, soap, etc), sitting in my basement. And I haven't bought rice not-on-sale in forever, because I can afford to find a sale and buy a bunch at once.
