Black Friday big screen TV sale, it doesn't get any better than this. Best Buy is selling a 70-inch Samsung TV at a huge discount, but we're not sure how long it will last.

Right now Best Buy is selling a huge 70-inch Samsung 6 Series 4K TV for $529.99. This impressive set is regularly priced at $749.99, so you save $220 if you act on the top Black Friday sale. As of this writing, you won't find a TV of this size cheaper anywhere.

If you have room for this 70-inch TV, you can turn your home entertainment center into a mini movie theater. The best part? No one needs to know that you got your brand new set for a fraction of the cost.

This Samsung set runs on the company's Tizen smart TV platform, meaning you can watch content from most (if not all) of your favorite streaming platforms. In addition, an ultra-fast crystal processor converts all the content you watch into crisp 4K quality.

It would be nice if this TV had more than two HDMI ports, but given the price, we can't complain. If you're looking for something with more output ports, check out our ongoing TV deals.
