I stocked up on Listerine last week… here is my Listerine scenario:
Buy 4 Listerine 500 ml (they must be 500ml in order to qualify for the SCR) $3.49 each…for a total of $13.96
Use 4 $1/1 Q’s here
Total = Free with $0.04 overage
Note: The regular Listerine 500ml is this price… not the fancy, smancy whitening Listerine
