From Rayovac's web page - you can like Rayovac on Facebook and get an IP for $1/1 (any). Goes well with the current week's sale!

The cashier may give you trouble because Ingles has been burned badly by this deal recently - several individuals have been printing and copying this coupon for lots of free batteries so Ingles is quick to label any Rayovac coupon a scam. Ask for a manager and talk them through how you got the coupon - it's hard to argue when the coupon is directly from the manufacturer and not a PDF!
