Amazon is discounting its refurbished devices until 11:59 p.m. PT tonight - here are the best deals on the Echo Show, Kindle Paperwhite, and more

Looking to bring some smart features to your living room? The Amazon Fire TV Stick 4K is worth considering. The device supports 4K streaming and allows you to install apps like Netflix and Hulu quickly and easily. It even has Alexa built right into it, meaning you can use your voice to play movies and TV shows, or control your smart home, search on the web, and so on.

Prefer diving into a book rather than watching TV in your free time? The Amazon Kindle Paperwhite is one of the best ebook readers Amazon has ever released, offering a ton of storage, a backlight for reading at night, and so on. With the Paperwhite, you'll be able to take hundreds of books on the road with you, and access Amazon's massive library of millions of ebooks.

You've likely heard of the Amazon Echo smart speaker, which was the first smart speaker with Alexa built into it. Using your voice, you can control smart home devices, order food, and so on. If you want a slightly more visual experience, it's also worth considering the Amazon Echo Show, which can display information like weather, upcoming calendar events, and so on.

Looking to increase the security in your home? A video doorbell is a good buy. With the Ring Video Doorbell, you can see footage from outside your door on your phone, and see who's at your door from afar. You can even chat with the person at your door when you're not home. The Video Doorbell Pro is also on sale, boasting a slightly more refined design and a better video resolution.
