Black Friday is looming large on the horizon, promising big discounts on TVs, laptops, headphones, speakers, and just about everything else. It's the single best time of the year to shop, with deals on offer from all the leading retailers.

Another key advantage of shopping on Amazon during Black Friday is their price guarantee: If you purchase an item and its price drops before December 2nd, Amazon will refund you the difference. This assurance means that you can buy with confidence and know that you’re getting the best possible deal without having to wait for prices to drop further.

Best Buy's official Black Friday sale is live now — and I'm vetting the very best deals and doorbusters for you. From now through actual Black Friday (November 29), you can expect the latest and greatest tech deals from popular brands like Apple, Sony, Ninja, Dyson and more.
