As one of its daily deals, MidnightBox offers the Powerpack AAA Alkaline Battery 100-Pack for $13.95 plus $3.99 for shipping. That's $0.18/battery, $2 under our mention of a similar 100-pack from three weeks ago, and the lowest total price we could find for this quantity elsewhere by a buck, outside of the price below.
