Update: these WERE $1.98 at modesto (mchenry) store!!!
It is being reported that Target has their Listerine Whitening rinse marked down to $2, use the $2 printable coupon available to get it FREE! I have not confirmed this deal in our area, and my sister said the only ones she saw on sale were the regular Listerine, but if I find out, I will update the post.
*Use zipcode 01364, otherwise you'll probably just get a $1 coupon.
