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.
