Listerine Total Care: buy 2 for $9 = $4.50 a piece.
Print two coupons
Use 2 $2/1 printable coupons (not sure how..after the first print click the Back button 4 times and another will print) So now you have subtracted $4.00 down to $5.00

Remember I am the blogger who doesn't really believe that FREE is FREE unless I don't spend anything out of my pocket, but you can use the $4.50 RR at any store to pay for your items because it is a manufactured coupon.
