Staples offers the Dell S2817Q 27.9" 4K LED-Backlit LCD Ultra HD Monitor for $269.99 with free shipping. That's the lowest price we could find by $30 and the second-best price we've seen. (The best was our last mention, which was for $20 less on Cyber Monday.) It features a 3840x2160 (4K, 2160p) native resolution, dual 9-watt speakers, USB 3.0, DisplayPort, and two HDMI inputs.
