Samsung 55" (UN55MU6300FXZA) $349 Walmart In Store Only - YMMV!!
I was looking at Walmart for something else when I stubbled across this: SAMSUNG 55" Class 4K (2160P) Ultra HD Smart LED TV (UN55MU6300FXZA) for only $349!
The link is for information only, as they do not sell it online anymore. But it seems like a pretty good deal. It seems to be at this price a lot of locations at this price. This is a in store deal only, and obviously YMMV!
