Sears offers the Ultralast AA Alkaline Batteries 8-Pack, model no. ULA8AA, for $1.99. Plus, Shop Your Way Max members bag free shipping. (Not a member? It's free to sign up for a 90-day trial; otherwise, shipping adds $5.99.) That's $0.25/battery, the lowest total price we could find by $4, and the least expensive 8-pack of AA batteries we've seen.
