Coupons.com has reset the $1/1 Renuzit coupon on the Super Odor Neutralizer.  The coupon pictures the spray, but can be used (with no beeping) on any of the Super Odor Neutralizer adjustables that are selling for a buck or less.  I would not wait on printing this because last time it reached its print limit quickly.

Walgreen’s has this on sale with in-ad coupon for .99.
Walmart has them regularly priced at .94 – which means cash back!
Target has the single packs for .85.  Your overage mileage may vary.
