If you're thinking of doing the 2/$9 Listerine deal and have not yet, be on the lookout for special bottles. I did the deal twice this morning: two of my bottles had 50% more free, making each 1.5 L: and the other 2 bottles each had a free 250 ML bottle attached it it. So I actually got 5.5 L of Listerine for the price of 4, and got the RR!
