Speaking of Shark’s website, it’s also worth checking the daily sales the site is running, and the latest promo codes on WIRED. You’ll often find $100 off products like the everChange Air Purifier Max, the Matrix robot vacuum, and the cordless PowerDetect.

If you’re buying a Shark vacuum for the first time, you’re in luck: you can get 10 percent off right away by signing up for Shark’s emails. You’ll be prompted to put your email in, and will be emailed a unique code for you to use to get 10 percent off your order of a single item. That item doesn’t have to be a vacuum—feel free to snag your own Shark FlexStyle, an air purifier, or even a red light mask.

If you’ve already had your first order on Shark’s website, all is not lost. You can refer a friend to get them a $20 discount on orders over $100 on Shark’s website. You’ll score a $20 discount for yourself, too, once that referral code is validated, though you’ll need to spend $200 to use it.
