As one of its doorbuster deals, Dell Small Business offers the Dell 24" 1080p IPS LED Monitor bundled with a $75 Dell Gift Card for $209.99 with free shipping. Assuming you'll use the gift card, that's the best price we could find by $35 and the best deal we've seen. (For further comparison, we saw it for $150 a month ago.) It features a 1920x1080 (1080p) resolution, HDMI, and USB 3.0 ports.
With these companies, it might be easier than you think to negotiate your monthly bill down.
