For in-store pickup only and with stock varying by ZIP code, Walmart offers the Hisense 54.6" 4K HDR LED-Backlit LCD Ultra HD Smart Television, model no. 55H6D, for $398. That's tied with our mention from a month ago, $70 off, and the lowest price we've seen. It features a 3840x2160 (4K, 2160p) native resolution, full-array LED backlight, 4K upscaling, built-in dual-band WiFi, Smart TV apps (including Netflix and YouTube), three USB inputs, and four HDMI inputs.
