If you live near a Walgreens, stop by this week to pick up the Airwick iMotion for free! These are on sale for 50% through Saturday which should make the price $3.99. There was a $4 off 1 coupon in the 8/8/10 Smart Source coupon insert! If you did not receive that coupon, you can also sign up HERE to print off a $4 coupon.
Please note that since the coupon exceeds the item the register will probably beep. The cashier should just adjust the coupon down 1 penny making the item free.
