There are a bunch of new Airwick coupons available today- including a $4/1 Airwick Freshmatic coupon.
I have two deals you can check out on the Freshmatic kits:
{CVS}
Starting next week (4/10):

Buy 4 Airwick Freshmatic Starter kits at $6.00
use (4) $4/1 printables or printable
Pay $8 and get a $10 ECB back for spending $20 on Airwick! So that small profit should help to cover tax.

(Thanks Frugal Living and Having Fun)

Also, I mentioned these Airwick Freshmatic Ultra starter kits at Target for $4.99 a few weeks ago.
The $4.99 price is valid through 4/10 however at Target yesterday I noticed these are on clearance for $4.24.  So worst case you pay $.99 but if you keep an eye out, you might even get them cheaper than .24 after coupon!  I saw these on an end cap and not on the regular fragrance aisle.
