Cheapest we've seen by $30 after a mail-in rebate
Want to outfit your home theater with 3D capability and better sound than you'd get from small flatscreen speakers? This LG 3D TV is only $450 after rebate and includes a sound bar and four pairs of 3D glasses.
$450, free shipping: 42" LG 3D LED TV with sound bar and 3D glasses
Don't forget the $100 mail-in rebate.
Reviews are very positive. If you're looking for a medium-large TV with modern functionality (other than Smart TV, which you can add later with a Roku), this one's way too inexpensive to overlook.
