HP takes $150 off this Quad Core Pavilion Laptop, dropping it to $599.99 with free shipping. Stack that with code MULN4163, which cuts it to $524.99. This is the lowest price we've seen on a quad core-equipped laptop, especially one with a blu-ray drive. It also features 6GB of RAM for smooth running even of HD media or elite games. The blu-ray drive and LED HD screen make it a great option for movies as well. Most states charge sales tax.
