Throughout Prime Day, one of the best Prime Day TV deals wasn't even on Amazon. Instead, there was a Best Buy offer on a 70-inch Samsung TV with a big screen and big savings. But there's no telling how long this campaign will last.

So we suggest jumping on Best Buy's offer of a 70-inch Samsung 6 Series 4K TV for $529.99. This huge set is regularly priced at $749.99, so you'll save $220 if you act on this Prime Day TV sale. Simply put, you won't find a TV of this size cheaper than this.

There is something about a 70-inch TV that grabs attention in a room. If you have the space for a set this size, you can transform your home into a movie theater. Of course, no one needs to know that you got your brand new centerpiece 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 Best TV Sales and Best Prime Day TV Sale deals. We're monitoring all the top sales on top sets around the clock.
