Welcome to our Black Friday TV deals live blog! On this blog I'll be highlighting the best TV deals on 4K TVs, OLED TVs, Mini-LEDs, and more. If there's one deal I'm particularly excited about right now it's this one. Best Buy has the LG B4 48-inch 4K OLED TV on sale for $699. That's the cheapest OLED TV I've seen all year. To be fair, it did hit this price back in September, but it's a solid deal if you're looking to buy your first OLED and don't have a big budget. If you can afford it, I recommend going for the 65-inch model (currently at an all-time price low). You'll never regret the extra screen real estate. Note: The 48-inch model is a Best Buy exclusive.
