The Olay Pro-X Advanced Cleansing System falls from $29.99 to $18.99 to $15.99 when you clip this coupon at Amazon. If you have Amazon Prime, it ships for free, but even with $5.48 for shipping this is the best deal we've ever seen for this cleansing kit. It includes one two-speed exfoliating & cleansing brush, an 0.68 oz. tube of Exfoliating Renewal Cleanser, and two AA Duracell batteries for use with the brush. Sales tax is charged in most states.
