Walmart has the 55mu6290 for $300 at some stores after pickup discount. Only one store in my area had it at this price (49735).
This is a well rated TV than can be upgraded to the MU6300 series’ features in the service menu. https://www.rtings.com/tv/reviews/samsung/mu6290 The smart remote can be picked up for about $25 from various sellers. I snagged a 40" version of this from a previous deal, and it has an amazing picture. It lacks local dimming and a wide color gamut, but, at this price, it’s an amazing deal.
