Priced at $579 at three stores in my area, but on clearance in a fourth store for $429.31.
Apparently, Sam's locations drop their price on TV's once they only have a couple units in stock, and don't plan to order more. So definitely a YMMV, but I'd expect more and more stores to be ridding their shelves of these.
No, it's not OLED. Yes, there are better TVs available at the $550-650 price point. But at $430, this is a decent price for a 70" Samsung.
