One of the more affordable and useful gifts for tech buffs is a media streamer, from Roku to Chromecast and beyond. This holiday season, you can nab one of these gadgets for as little as $25, and be streaming your favorite movies or binge-watching a TV show in no time.
But where can you get the best deals on Black Friday? The big box stores and online retailers are all offering discounts on the most popular streamers. Check out your best bets below.
ROKU
Roku went above and beyond in releasing a brand-new device just for this holiday season. The Roku SE runs the company's newest "built-for-TV" operating system, Roku OS 7, which launched with its pricier 4K device. 
It offers 1080p video streaming with a "simple user interface," and gives you access to nearly 3,000 streaming channels, including 300,000 movies and TV episodes. And on Black Friday, it will be just $25 on Roku.com, as well as Best Buy, Walmart, and Kohl's, and other retailers, too.
The Roku 3, meanwhile, will be $79.99 on Black Friday via Roku.com and stores like RadioShack and hh gregg. At Fry's, it will be $68 with a special promo code, but you need to sign up to receive one ASAP.
With a Fry's promo code, you can also nab a Roku Streaming Stick for $34 (down from $49.99). Otherwise, it will be $39.99, as it will be at other retailers like Best Buy, the Microsoft Store, Office Depot/Office Max, and Sam's Club.
CHROMECAST
Google upgraded its Chromecast devices earlier this year, and now offers the colorful Chromecast dongle for HDTVs and the Chromecast Audio for streaming music, both of which retail for $35. On Black Friday, several stores will be offering two Chromecasts for $50, a $20 discount, including Best Buy, Costco, Staples, and Office Max/Office Depot.
The second-gen Chromecast will also be $29.99 at hh gregg, a $5 discount.
Walmart will be selling the older Chromecast for $20; likely trying to get rid of its supply. To see the differences between the first- and second-gen device, check out Which Chromecast Is Right for You?
Just don't go looking for any discounts on Amazon.com.
APPLE TV
Apple TV is another product yanked from Amazon.com since it doesn't provide access to Amazon Prime Video. But there are plenty of other places to get your hands on one. The older Apple TV, currently on sale for $69, will be $10 cheaper at stores like Target, though it's already $59.99 at hh gregg.
It does not appear that the newer Apple TV will get much of a discount this Black Friday, though Apple has not announced its deals just yet. Hh gregg is actually selling the 32GB and 64GB Apple TV at a $20 discount right now, though both listings say the device is out of stock.
AMAZON FIRE TV
Amazon has promised eight days of savings this Black Friday, which lasts until the end of this week and then kicks off again for Cyber Monday. Not surprisingly, its Fire TV devices are on the list for discounts, but Amazon doesn't get specific when it comes to when its deals will go live. But keep your eyes open for
Best Buy will also have the Fire TV Stick for $24.99, down from $39.99.
The Amazon Fire TV will be $74.99 at Staples, a $25 discount.
