Run to Walmart to see if your store has General Mills Honey Nut Cheerios on clearance! Our store has them on clearance for $1.50. Use a newspaper coupon from the 7/9 Smart Source insert to pay $0.75 in the store. Then scan your receipt after purchasing for an additional $0.50 credit, making a box only $0.25.
Remember, clearance varies from store to store.
