Best Buy offers the Dell S2330MX 23" 1080p LED-Backlit Widescreen LCD Monitor for $154.99 with free shipping. That's the lowest total price we could find by $12, although it was $5 less in December. Sales tax is added where applicable. This ultra-slim display features a 1" panel depth, 1920x1080 (1080p) native resolution, 1,000:1 contrast ratio, 2.5ms response time, 250 cd/m² brightness, DVI-D and VGA inputs, and more.

Update: Best Buy has since sold out for delivery, so you'll need to choose in-store pickup. However, Amazon now charges the same and includes free shipping.
