Most retailers sell this for over $6000 after the Cashback promo!!
I am personally a fan of OLED's for their deep blacks and I own one (and love it!), but I have been reading a lot about Samsung 2018 QLED's and their peak brightness simply blowing OLED's out of the water….so,if you're questioning the cost of this tv, use the 2018 OLED's from LG/Sony/Panasonic with similar size/specs for reference which makes it a fair comparison.
