Office Depot and OfficeMax again offers the Duracell Coppertop Alkaline AAA Batteries 16-Pack or Duracell Coppertop Alkaline AA Batteries 16-Pack for $14.99. Plus, Office Depot and OfficeMax Rewards members will bag a $14.98 Rewards Credit for free. (Not a member? It's free to sign up.) With free shipping and assuming you'll use the credit, that's essentially free and a great deal on AAA or AA batteries, although we saw them for a buck less in June. (It's the best deal we could find now by at least $9.) Deal is limited to two per customer and ends September 2.

Note: Allow up to five weeks after the promotion ends for Rewards to become available in your account.
