Newegg offers the refurbished HP ENVY TouchSmart AMD A10 Quad 2.5GHz 15.6" Touchscreen Laptop, model no. 15-j073cl, for $499.99 with free shipping. That's $200 off and tied with last month's mention as the best price we've seen for an HP Envy with 12GB RAM. It features an AMD A10-5750M 2.5GHz quad-core processor, 15.6" 1366x768 touchscreen LCD, 12GB RAM, 1TB hard drive, 802.11n wireless, webcam, 6-cell battery, and Windows 8 64-bit. (No optical drive is included.)
A 90-day warranty applies, although it's unclear who backs it.
