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 is dropping big Black Friday deals now and this 75-inch 4K Roku TV is going to sell out faster than ever at less than $380. Here's when to grab it.

This Lenovo Ideapad 3i laptop is now even more budget-friendly thanks to a $390 discount at Walmart. It comes packing an Intel Core i7 processor, 16 GB of RAM and a 512GB SSD. It also boasts a 15.6-inch FHD display with ultra-thin bezels.
