Because Walmart likes to release its most jaw-dropping TV deals as a handful of pre-meditated doorbusters, more shoppers will be waiting in the wings for the clock to strike a certain time (rather than calmly perusing several pages of TV deals) — which means TVs selling out is more likely and time is of the essence.

Another standout offer is the LG B4 48-inch OLED TV for $599.99 (was $799.99). That's the lowest price yet for the manufacturer's best cheap OLED TV. It's a great buy if you need a smaller yet still high-quality display for watching shows, movies and gaming.

Known for their perfectly inky black levels, eye-popping color, and their cutting-edge features, OLED TVs frequently top best-of-year lists and Black Friday sales headlines. This year, many of the best OLED TVs you can buy are at their lowest price ever.
