Today only, Sam's Club offers members the Vizio SmartCast 55" 4K 2160p WiFi LED-Backlit LCD Ultra HD Home Theater Display, model no. E55-E1, for $428 with free shipping. That's $122 less than our mention from three weeks ago (although that included a $200 Dell gift voucher) and is the lowest price we've seen. (It's the best deal now by $120.) It features a native resolution of 3840x2160 (2160p), Vizio SmartCast technology with integrated Google Cast, USB, and four HDMI inputs.

Note: Non-members can sign up for a 1-year membership for $45; otherwise, you'll have to pay a 10% surcharge.
