Best Buy’s “48-hour” weekend flash sale was a historical promotion that ended on September 28, 2025. The headline deal was a 75-inch TCL QM5K QD-Mini LED television listed at $599.99, but every price below is a September 2025 figure—not a live August 2026 offer. Check the direct Best Buy listings for current price, stock, seller, and delivery details.
What the promotion was—and why the date matters
HotHardware reported the event on Sunday, September 28, 2025, describing it as a 48-hour Best Buy flash sale ending that day. “Ends today” was accurate in that publication context; it does not mean the promotion is active now. The report did not establish whether every item was sitewide, member-only, inventory-limited, or subject to special fulfillment rules, so those terms should not be assumed.
The original roundup linked to Best Buy’s electronics sale page. A product page can remain online after a promotion, redirect, sell out, change seller, or show a different configuration. Treat the amounts below as historical reference points, not promises of current savings.
The headline value deal: TCL 75-inch QM5K
Best Buy listed the TCL 75-inch QM5K at $599.99, with a claimed $600 reduction from MSRP. That combination of screen size and quantum-dot Mini-LED hardware made it the strongest value-oriented offer in the roundup—but an MSRP comparison is not proof of the lowest recent street price.

The gaming specification that needs careful reading
The listing identified a native 60Hz panel while advertising “Game Accelerator 144.” Those are not interchangeable claims. Game Accelerator 144 suggests variable-refresh-rate gaming support in supported modes; it does not turn the panel into a conventional native-144Hz television. Before buying, verify the supported resolution-and-refresh combinations, VRR range, HDMI 2.1 functions, and which inputs can use the advertised mode.
The QM5K therefore suited shoppers prioritizing a very large screen and Mini-LED contrast at a value price. Serious high-refresh-rate PC or console gamers should treat the 60Hz native panel as a material compromise.
Pixel Watch 3: a discounted previous generation
The 41mm Wi-Fi Google Pixel Watch 3 was listed at $199.99, a claimed $50 reduction. Google had unveiled the Pixel Watch 4 by the time of the sale, so this was a prior-generation clearance-style purchase rather than a discount on the newest model.
Rank #2

Two laptop deals, two different buyers
| Model and historical configuration | September 2025 price | Best fit | What was not established |
|---|---|---|---|
| Lenovo IdeaPad 1i: 15.6-inch display, Core i5-1334U, 16GB RAM, 512GB SSD | $479.99; claimed $220 saving | Schoolwork, office applications, browsing, and general productivity | Display quality, battery life, build, ports, graphics, and gaming performance |
| Lenovo Yoga 7: 16-inch 2K touchscreen, Ryzen 7 8840HS, 16GB RAM, 512GB SSD | $629.99; claimed $320 saving | Buyers wanting more processing headroom and a convertible touchscreen | Battery testing, graphics capability, ports, and display behavior |
The Yoga 7 cost $150 more in the historical listing but offered the stronger processor and 2-in-1 design. If you do not need a convertible touchscreen, the IdeaPad’s lower price may be the more rational choice; demanding creative or gaming workloads require checking the unreported graphics and cooling details.
Rank #3
- QD-MINI LED | BRIGHT WHERE IT SHOULD BE, DARK WHERE IT SHOULDN'T: Get the deep blacks and precise contrast shoppers expect from a premium display, plus the high brightness Mini LED is known for. Up to 500 local dimming zones with TCL Halo Control Technology precisely control the backlight to reduce unwanted blooming around bright objects. The result is bright highlights, deeper blacks and greater contrast, without the burn-in concern associated with premium displays
- NATIVE 144Hz | BUILT FOR GAMING + SPORTS: Looking for a gaming TV or a better TV for sports? Native 144Hz, Motion Rate 480, VRR, ALLM and Game Accelerator deliver smooth, responsive gameplay and clearer fast-moving action. Follow the ball, catch every play or jump into high-speed gaming with greater motion clarity and responsiveness
- ONKYO 2.1 + BUILT-IN SUBWOOFER | HOME THEATER SOUND: Turn your living room into a home theater with Onkyo 2.1 audio and a 20W subwoofer for deeper bass, clearer dialogue and fuller sound. Dolby Atmos and dedicated DTS add immersive audio for movies, gaming, sports and streaming. With powerful sound built right into the TV, adding a soundbar is optional
- BEZEL-LESS DESIGN | MORE SCREEN, LESS FRAME: Make your entertainment feel bigger. The thin, bezel-less design minimizes the frame around the picture for a more immersive big-screen experience. Whether you're watching movies, streaming shows, sports or gaming, more of what you see is the picture, not the frame
- 1.07 BILLION COLORS + AiPQ PRO | BETTER PICTURE FOR MOVIES + STREAMING: A bigger screen should make your entertainment better, not just bigger. Enhanced QLED Color delivers up to 1.07 billion colors with a wide color gamut, while TCL's AiPQ Pro Processor intelligently optimizes color, contrast and clarity for movies, streaming, sports and games
Audio and premium-TV offers
AirPods Max: specifically the Lightning version
The Apple AirPods Max with Lightning were listed at $519.90, with a claimed $30.09 saving. This was not the USB-C revision. The connector distinction matters if you are standardizing on USB-C or want the newest compatibility features, so do not treat the listing as a generic AirPods Max deal.
LG G5 OLED: a luxury purchase, not a mainstream bargain
Best Buy listed the 77-inch LG G5 OLED EVO at $3,799.99, claiming $700 off. Its premium OLED positioning put it in a different category from the value-focused TCL QM5K: appropriate for a flagship home-theater buyer, not evidence that a $3,800 television was broadly good value.
Recommended Free Tools
TCL Q65H soundbar
The TCL Q65H was listed at $249.99, with a claimed $250 saving. The package included 5.1-channel audio, Dolby Atmos, Ray-Danz technology, and a wireless subwoofer. Value depends on room size, television connectivity, dialogue clarity, bass expectations, and whether rear speakers are included; a discounted soundbar is not automatically a substitute for a discrete surround system.
Rank #4
- HI - QLED MINILED: Striking contrast and vivid, lifelike color put every scene in a new light. Whether it's a sunny landscape or a candlelit drama, the picture leaps off the screen. Mini-LED backlighting uses hundreds of precise light zones to enhance contrast across the screen. Paired with Hi-QLED technology, every color comes through with stunning depth and accuracy
- NATIVE 144HZ REFRESH RATE: Fast breaks, high-speed chases, live finales — every frame stays crisp and fluid, so the action is always exactly where you need it to be. Native 144Hz refresh performance keeps movement fast and sharp, reducing blur during gameplay and live sports. The quick response helps you stay in control during competitive gaming while making rapid camera shots in shows and movies easier to follow
- BUILT-IN SUBWOOFER: Immersive deep bass from the built-in subwoofer pulls you into the heart of the moment, from the rumble of an explosion to the thump of your favorite song. Feel like you’re a part of the action
- ANTI-REFLECTION & GLARE-FREE: Bright rooms are no match for this screen. The anti-reflection and glare-free display keeps your view clean and distraction-free, so you stay focused on what matters — the show
- UNIBODY SLIM DESIGN: Edge-to-edge display and a seamless design that disappears into your room — so all you see is the picture

These figures and savings were reported for the September 2025 event by HotHardware; the article did not establish that any was an all-time low.
What to verify before treating any listing as a deal
- Open the official product page and confirm today’s price rather than relying on the archived figure.
- Match the exact model number, screen size, memory, storage, connector, and Wi-Fi or cellular configuration.
- Check whether the item is new, open-box, refurbished, marketplace-sold, or shipped only.
- Confirm stock, pickup location, delivery date, taxes, shipping, installation, and optional protection-plan charges.
- Read the current return and warranty terms; the 2025 article did not detail them.
- Compare the price with recent selling prices, not only the stated MSRP or “save” amount.
Bottom line for shoppers
In the historical roundup, the TCL QM5K was the clearest value play, provided you accepted its native 60Hz limitation. The Yoga 7 was the more capable laptop choice for buyers who valued performance and flexibility, while the IdeaPad 1i targeted basic productivity. The Pixel Watch 3 discount made sense mainly for shoppers comfortable with previous-generation hardware. AirPods Max buyers needed to accept Lightning, and the LG G5 was a premium splurge rather than a general bargain. None of these September 2025 prices should be treated as active without a fresh Best Buy check.
