The TCL 55R617 55-inch 4K HDR Roku TV is down to $499.99 at Best Buy. This TV normally sells for $550 at other retailers including Amazon. We've seen it drop consistently throughout the year, but today's deal is a new all-time low.

You could also upgrade to the 65-inch version of the TV for $899.99. It's a significantly larger investment, but it's also a significantly larger television. This isn't the best deal we've ever seen (it dropped to $873 in August), but it's $30 or more better than other retailers like Amazon.

The TCL 6 series is the best TCL Toku TV on the market. CNET gave it 4.5 stars and an Editor's Choice and called it "the best TV value we've ever reviewed." It's not that this is the greatest quality television or has the most advanced features. It's that what this TV says it does - it does very well. When we first heard about the 6 series, we broke down what you can expect from them. Read more about that here.
