Renuzit - Cheap at Cub And Other Stores

Today at Cub as I was picking up some more Glade Scented Oil Warmers, I saw a deal on Renuzit Tri Scents Starter Kits. For each one you buy, you get an OYNO coupon for $3. This is a Catalina type coupon.

They were priced at $8.77.
Use a $4/1 coupon from the 9/7 insert
Pay $4.77 OOP
Get $3 Catalina coupon to use OYNO (on your next order)
= $1.77 each!

Has anyone ever tried these? These might be another nice Christmas gift idea. If you're like me with three kids, you have LOTS of people to buy for at Christmas time.

I assume this deal is going on at other grocery stores as well. Let us know if you find it.
