If you don't care about 3D, this is an excellent deal
Oftentimes it's cheaper to just get a big "dumb" TV and add a Roku, Apple TV, WiFi Blu-ray, Chromecast, or other device to give it Internet streaming capabilities. But today, you can get your hands on a 55-inch LG LED Smart HDTV for only $700 in cart at Sears - nearly $100 cheaper than you'll find that model anywhere else.
Steam Netflix and Hulu Plus natively on this set. You'll have to buy a dongle if you want to connect via WiFi, but otherwise Ethernet'll work just fine and give you a better connection to boot.
