SAVE OVER $400: As of Nov. 12, the 55-inch LG B3 OLED TV is on sale for $798 as part of Walmart's early Black Friday sale. That is down $401 from its list price of $1,199.

Walmart has a deal on the 55-inch Samsung QLED 4K TV that will cost you less than $300 — but only during its "Black Friday Deals" sale. Here's when to grab this big markdown.

If you want to score a fantastic TV that's roughly the size of a queen-sized mattress, don't wait until Black Friday rolls around.
