The "March Madness" TV sale is underway this month, and Samsung is kicking off the weekend with a shocking sale on its 4K Smart TV.

Today only, Samsung's 55-inch 4K Smart TV is on sale for $499.99. That's $100 off and one of the best deals on TVs available today. It is also the cheapest Samsung 4K TV you can buy right now.

Available in 55-inch ($499) or 65-inch ($699) capacities, the Samsung TU8300 4K Crystal TV features an immersive curved display on whatever you're watching (or playing). This Samsung set runs on the company's Tizen smart TV platform, so you can watch content from most (if not all) of your favorite streaming platforms. In addition, an ultra-fast crystal processor converts all the content you watch into crisp 4K quality.

It also features HDR10+ support, built-in Alexa/Google Assistant, and an auto game mode that automatically optimizes the TV's input lag when it detects that a game console is connected and turned on.

However, this sale is only available for a few more hours, so you'd better act fast.
