I love free battery deals.  We keep a stockpile on hand.  It seems everything requires a battery nowdays.

In case you were wondering, Eveready is part of the Energizer brand (it states that on the back of the packaging). If you purchase $5 in batteries, it would be a $1 Money-Maker with the Target coupon! via Free Batteries at Target.
