Apply coupon code "VISACHECKOUT" and checkout with Visa Checkout to cut it to $329.99. With free shipping, that's tied with our August refurb mention as the best price we've seen for this TV. (It's also a current price low for a refurb by $157.) It features a 1920x1080 (1080p) native resolution, LED backlight, 120Hz refresh rate, WiFi, video apps such as Netflix and VUDU, USB, and four HDMI ports.
A 90-day warranty applies, however it's unclear who supports it.
