The TCL 55R617 55-inch 4K HDR Roku TV is down to $552.49 with code PRONTO15 through the electronic_express eBay store. It sells for $650 without the code and that's a standard price for most retailers. This TV just released in early May. We have seen it go on sale a couple of times, but these eBay sitewide sales are the best discounts we've seen.

The coupon code is part of an eBay site-wide sale taking 15% off of everything over $25. This TV is near the max of what you can save ($100 total), so you're getting a lot of bang for your buck from eBay's one-day sale.

You can also save on the previous generation of TCL TV. The 2017 55C807 TCL TV is down to $407.99 through the same authorized reseller and using the same code above. You can't buy both TVs on one account since the savings will max out, so you'll have to make your choice.

The TCL 6 series is the newest Roku TV on the market and also the best. CNET gave it 4 stars 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.
