Save money on groceries
Stockpile sale items
Many avid couponers stockpile large amounts of nonperishable groceries and toiletries purchased on sale. Carrie Kirby, a frugal blogger, once filled the entire cargo hold of her Subaru with cans of her favorite soda. "My basement shelves hold enough of things like toothpaste and cereal -- often purchased for 25 cents or less -- to last our family six months to a year," she said.
And if a family member gets ill or loses a job, you'll have a nicely stocked food pantry during a rocky time.
