Walmart offers the Polaroid 50" 4K HDR Flat LED Ultra HD Smart Television for $259.99 with free shipping. That's the lowest price we could find by $67, although most retailers charge $400 or more. (We saw it for $70 less in December.) It features a 3840x2160 (4K) native resolution, Smart TV apps (Netflix, YouTube, Vudu, more), and three HDMI inputs.
The dollar store is the most amazing place to find bargains for certain purchases. Yes, even pregnancy tests.
