For in-store pickup only, Walmart offers the TCL 55" 4K LED-backlit Ultra HD Roku Smart Television, model no. 55S401, for $398. That's tied with last week's mention and the lowest price we could find by $52. It features 2160p near Ultra HD resolution with 4K upscaling, content streaming via Roku TV (Netflix, Youtube, Hulu Plus, more), USB, and three HDMI inputs.
