Walmart has this 50-inch 4K Roku TV on sale in one of the best deals of the holiday season. Here's the deal that you can only score during its "Black Friday Deals" sale.

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.

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.
