With "CYBER30" code for 30% off, free ship-to-store, and two coupons you can clip right on the Walgreen’s web site (one Walgreens, one manufacturer’s, $3 each), my total was 7.99 pre-tax.
Regular price 19.99 – 3 (Walgreens coupon) – 3 (MFC) – 6 (30% off) = 7.99
Similar deal for Opti-free Replenish.
You can only use the coupons once.
