Amazon has discounted all of its own hardware - Fire TVs, Fire Tablets, Kindles & Echos - right now for Valentine's Day. Making this a great time to pick up a new Amazon Echo, or even a new Fire TV. The newest Amazon Fire TV is currently on sale for just $55, which is good for $15 off of its regular price and brings it back down to Black Friday pricing. The Amazon Fire TV is a great set-top box to pick up, because it does support both 4K and HDR, as well as also having a ton of apps available for consuming content.
With the Winter Olympics fast approaching, now is a good time to sign up for a free 7-day trial of DIRECTV NOW. Of course, if you want to have DIRECTV NOW for the duration of the Olympics (February 8th through the 25th), there is another promo you can take advantage of. DIRECTV NOW offers up an Amazon Fire TV if you pre-pay for 2 months of the service. Which comes out to roughly the original price of the Amazon Fire TV, but that's a great way to get an extended trial of the service.
All of the deals listed in this post are good through midnight PT on the date noted, unless otherwise noted. So you'll want to take advantage of them before they are sold out.
