Best cheap QLED TV deal: Insignia 75-inch is still $399.99 from Prime Day

SAVE $250: As of Oct. 14, the 75-inch Insignia QF QLED 4K Fire TV is on sale for $399.99 at Amazon. That's its same price from Prime Big Deal Days last week, and a 38% savings.

The cheapest 75-inch QLED TV we saw during Prime Big Deal Days in the first week of October is still at that price. You can still grab the massive 75-inch Insignia QF QLED Fire TV for $399.99 at Amazon — a nearly 40% price cut, dropping the TV to its lowest price ever. Amazon probably won't start teasing Black Friday deals until mid-November, so this is your chance to upgrade during the year's most elite cozy binge-watching months.

With this big of a steal on the table, you don't have to ride or die for your old LED TV anymore. Curse it out one last time, recycle it at Best Buy, and start building a new fall watchlist for you and your new big screen. We recommend Tim Robinson's The Chair Company, or if you're strictly in spooky season right now, we have a full interactive horror recommendations builder — just tell us what you're into, and we'll give some suggestions. We've seen everything.

If you've never had a QLED TV at home before, it's hard to envision what "quantum dots" even mean. In the simplest sense, they're an extra layer of tiny light-reflecting crystals on top of the LED backlight that your old TV had. QLED TVs are best known for brightness and boosted color saturation, and you'll notice that difference in vibrancy the first time you turn on a football game midday... and can actually see what's going on.
