Rayovac Facebook Coupon $1/1

Rayovac has a coupon available thru Facebook for a $1/1 any pack of Rayovac Alkaline Batteries
In the past I have got the 2 pack at the dollar spot at Target, so FREE batteries.
Go here and "Like" Rayovac and then click on the "promotions" tab and on the bottom left,you will see where it says to print your $1/1 coupon.  Mine shows an expiration of 6/30/2010.
