This new $1.00/1 Renuzit Super Odor Neutralizer coupon can be used on the adjustable cones (it doesn’t specify that you have to use it on spray).   You should be able to them at Walmart, Target and many other retailers to get them FREE after coupon.  If you don’t see the coupon, I found it under zip code 56001 and in the Household category.

Thanks, Rose Knows Coupons!
