Check out this awesome deal at Walgreens:
Lysol Freshmatic Refill on sale for $3.50,
it's FREE with this $4 coupon
Read Hip to Save for details.
Check out all their coupons for Airwick, Finish and Lysol. I would personally do this deal at Wal-Mart and price-match it there to get the overage. I wonder if these work with the Air Wick Freshmatic. Because refills without the thing to RE-fill is pretty silly. But call me coupon crazy, I think I'll still get it anyway!
