Best Buy's 48-Hour TV Flash Sale Ends Tonight With Record-Low Prices

Best Buy has launched a 48-hour flash sale ending at midnight, with record-low prices on best-selling 4K, QLED and OLED TVs and savings of up to $1,100, according to TechRadar. The retailer's deals include LG, Samsung, TCL, Insignia, Roku, Hisense and Toshiba models.

The sale includes limited-time offers, and TechRadar said shoppers may not see similar discounts until Best Buy's official November Black Friday sale. Among the highlighted deals, TechRadar listed LG's 48-inch B6 OLED TV at $799.99, reduced from $1,199.99. It called the B6 the best budget OLED TV of the year and noted four HDMI 2.1 ports for 4K gaming at 120Hz, variable refresh rate modes, HGiG and Dolby Vision Gaming support. TechRadar's main criticism was that the B6 did not offer a massive upgrade over the previous LG B5 model, though it still called it a fantastic entry-level OLED TV.

For mid-size budget buyers, TechRadar pointed to a 55-inch Insignia F50 Series TV at $199.99. The set has 4K resolution, DTS Studio Sound, Fire TV smart capabilities and a voice remote with hands-free Alexa. Best Buy also has the 55-inch 2025 Samsung Frame QLED TV on sale at what TechRadar described as its lowest price yet. The Frame features Pantone art-validated colors and comes with Streams, a complimentary set of artwork streamed from the Samsung Art Store.

TechRadar also listed Insignia's F70 Series QLED TV, which uses Mini-LED and Quantum Dot technology and includes Dolby Atmos audio, the Fire operating system and a voice remote with hands-free Alexa. Roku's best-selling 55-inch 4K QLED smart TV was listed at $99.99, with TechRadar citing its 4K resolution, QLED display, enhanced voice remote and Roku's smart TV interface.

The article gave conflicting prices for one TCL model. In its highlights, TechRadar listed the TCL 55-inch QM6K Series Mini LED QLED TV at $599.99, down from $799.99. Later in the same article, it listed the 55-inch QM6K at $499.99 and called that the lowest price it had ever seen. TechRadar did not explain the difference. It described the QM6K as a great budget mini-LED TV with vibrant picture quality and solid gaming features.

Other deals included Insignia's QF Series QLED TV at $240, a mid-size QLED set with 4K Ultra HD resolution, Quantum Dot technology, Dolby Atmos audio, Fire OS and a voice remote with hands-free Alexa. TechRadar also highlighted the 65-inch LG C6 at a record-low $1,599.99. It called the C6 its best-rated TV and said the 2026 OLED delivers more accurate, brighter colors than the C5, with contrast from a new Alpha 11 AI processor, gaming features and LG's smart TV platform.

Samsung's S90H, a mid-range OLED for the company's 2026 lineup, was also included. TechRadar said it supports 165Hz and advanced AI upscaling but uses a slightly lower-end WRGB OLED panel. In hands-on testing, TechRadar praised its anti-glare technology and overall picture quality, calling it a solid competitor to the LG C6. The Hisense U7 Series was highlighted for a bright QLED panel, strong contrast and a 165Hz refresh rate, which TechRadar said would suit sports, streaming and gaming.

For a cheap big-screen option, Best Buy has the popular 75-inch Toshiba C350 4K Fire TV at $399.99. TechRadar said the C350 supports HDR and delivers solid picture quality for everyday viewing, with the Fire TV operating system providing easy access to streaming apps such as Netflix, Disney+ and Prime Video. TechRadar's earlier highlights also included a 75-inch TCL 4K Smart TV at $479.99, reduced from $649.99.
