Dell Home, via its Member Purchase Program, offers the Dell Ultrasharp 24" InfinityEdge LED-Backlit LCD Monitor with Arm, model no. U2417HA, for $303.99 with free shipping. That's tied with last week's mention as the lowest total price we've seen. (It's also the best deal now by $46.) It features a 1920x1080 (1080p) native resolution, 8ms response time, HDMI input, and fully adjustable arm.
Note: Dell's MPP is available to select groups, including students, government employees, military (active and retired), credit union members, and health care workers.
