Invite your friends to join the Rayovac eClub just in time for Back to School! When 4 of your Friends join the eClub you will receive $4 in savings and each friend $1 off Rayovac coupon for joining! I don’t know about you, but my son tends to require a lot of batteries! And he is always removing batteries and adding more just so he can “fix” things! I am always having to figure out which ones are good or bad.
