Whether you choose one of Casper’s award-winning foam or hybrid mattresses or want to save on pillows, this sale is a great opportunity to save on essential sleep.

Water pik

A water flosser is an effective alternative to string floss, which sprays a stream of water onto your teeth to remove up to 99.9% of plaque. While you might be reluctant to add another tool to your bathroom, this one is compact and portable, meaning oral health doesn’t have to be a major annoyance. This discount is just shy of the lowest price we’ve seen on the Waterpik in 2022, so buy now – your dentist (and teeth) will thank you.


Pet hair and crumbs leaving your floors are a thing of the past with a quality robot vacuum. Fortunately, the iRobot Roomba i3+ is currently heavily discounted in refurbished condition.
