Walmart offers the Panasonic eneloop AA Rechargeable Batteries 8-Pack for $15.55. To drop the price to $14.85, opt for in-store pickup. That's a buck under our mention from last month and the lowest outright price we've seen. (It's also the best deal we could find today by $4.) They're rechargeable up to 2,100 times.

Update: The price is now $15.46 before in-cart discount, $15.31 after.
