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.

Walmart's Black Friday sales kick off on Monday, Nov. 25 and this Hisense 55" Smart TV is going to be only $178.

Zappos: Enjoy stellar savings on a wide variety of footwear brands at the retailer's Black Friday sale, including Hoka, Reebok and more, as well as great deals on clothing and accessories from Columbia, Michael by Michael Kors and other big names.
