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.

LG's 55-inch B3 OLED TV normally retails for $1,199. As of Nov. 12, it's on sale for $798 as part of Walmart's early Black Friday sale.

If you're ready to get a head start on Black Friday shopping, Walmart is officially open for business. Although the retailer's main Black Friday event doesn't launch until November 25, there's plenty of juicy deals to shop in the meantime.
