Deals on Discount Batteries

Groupon again offers the Sony Stamina Plus AAA Battery 72-Pack or the Sony Stamina Plus AA Battery 72-Pack for $15.99 plus $3.99 for shipping. At $0.28 per battery, that's tied with our mention from eight days ago and the lowest total price we could find for this quantity for either battery type by $22. Deal ends August 1 at 1 am ET.

Meh.com offers the Rayovac AAA Alkaline Battery 48-pack for $6 plus $5 for shipping. That's the lowest total price we could find by $3. These batteries can purportedly last unused for 10 years.

Also available is the Rayovac AA Alkaline Battery 60-pack for $8 plus $5 for shipping. That's the lowest total price we could find by $10. These also are purported to last unused for up to 10 years.

Of note, at checkout you can opt to purchase a monthly $5 VMP Membership, which bags free shipping on your current order, and orders made within the next 30 days. Since it costs as much as the $5 shipping fee, you may want to consider this option if there's any chance you'll buy something else from Meh.com (even though they'll do their best to talk you out of it). However, it is an automatically-recurring charge, so if you're not going to shop at Meh.com, you'll want to cancel it before your 30-day period is up.

Sears offers the DieHard AAA Alkaline Battery 24-Pack for $5.97. Opt for in-store pickup to avoid the $5.99 shipping charge. That's pennies below our February mention and a very low price for name-brand AAA batteries. These batteries have a purported a 7-year shelf life.

Of note, Shop Your Way Rewards members will earn a Sears credit with this purchase and may be eligible for additional credits and discounts.
