SkySeaCloud via Amazon offers the Olaxer 2-in-1 Rechargeable Facial Cleansing Brush (pictured) bundled with the Momoup 5-Piece Makeup Brush Set for $37.98. (Add them both to your cart.) Apply coupon codes "JBXCVWAG" and "7TJ9FRUE" to cut that to $16.99. With free shipping, that's essentially a free brush set, a savings of $11, and the best price we could find. (We last saw the cleansing brush, unaccompanied, for $3 more in January.) Deal ends May 20.

The cleansing brush features bi-directional rotation and auto shut-off. The set includes five different types of brushes.
