Caffeinate the fam with a 2-in-1 Keurig on sale for Cyber Monday

SAVE $49.99: As of Dec. 1, the Keurig K-Duo Essentials coffee maker is 50% off at Walmart for Cyber Monday. You'll pay $50.

Hosting family this holiday season? They're going to need coffee. And if you're relying on a single-serve coffee maker to caffeinate all your cousins and their assorted significant others, be warned: Disaster is coming.

The solution? Perhaps a Keurig K-Duo Essentials coffee maker that can brew both ground coffee and K-Cup pods. Cup and carafe sizes vary according to your needs: eight, 10, and 12 ounces for cups and eight, 10, and 12 cups for carafes.

There's also only one water reservoir for both sides, which means it's easy to use and even easier to teach someone else to use — great news for your uncle who hasn't listened to a single thing you've said since 2004.

Sound like something you could use? Snag it while Walmart's Cyber Week deals last.
