Amazon offers Prime members its AmazonBasics High-Capacity Rechargeable AA Battery 8-Pack, model no. HR-3UTHA-AMZN, for $15.99 with free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $6.38.) That's tied with last week's mention, $4 off list, and the lowest total price we could find.
