Sears offers the DieHard AA or AAA Alkaline Battery 24-Pack for $5.99. Plus, Shop Your Way Max members receive free shipping. (Not a member? It's free to sign up for a 90-day trial; otherwise, shipping adds $6.50. Free in-store pickup is also available.) That's tied with our December mention and the lowest total price we could find for either size by at least $14. These batteries have a 7-year shelf life.
