Amazon offers Prime members its AmazonBasics AAA Rechargeable Batteries 8-Pack for $9.99 with free shipping. (Non-members can check out via Subscribe & Save to bag free shipping, but be sure to cancel your subscription once your order ships.) That's $2 off, tied with our mention from September, and still the lowest price we've seen for these Japan-made batteries. They come pre-charged and last through 1,000 recharge cycles.
