Rice is a survivalist’s staple: some agriculture departments put its shelf life at as much as 30 years. At the very least, it’s good for two years. So don’t shy away from getting a big bag. At Frugal Foodie’s local Associated Market, 20 pounds of store-brand brand long-grain rice will set you back $10.49, or $0.52 per pound. A two-pound bag, meanwhile, is $0.75 cents per pound. (Total savings: $4.60.) Opt for brown rice to go cheap and healthy.
