Walmart continues to offer the Proscan 55" 4K 2160p LED-Backlit LCD Ultra HD Television, model no. PLDED5515, for $299.99 with free shipping. That's tied with our mention from last week and among the least expensive new 55" 4K UHD TVs we've ever seen. (It's the best deal for this model now by $50.) It features a 3840x2160 (2160p) native resolution, USB, and three HDMI inputs.
