Came across this and though it was a good price for a great set. This is the KS800D identical to KS8000 just made for stores like Costco/Sams Club to avoid price matching.
Shipping to store is free, or $49 to your house. Personally I would inspect the TV before leaving the store with it as Walmart refurbs are a crap shoot and screens can arrive broken.
Outside of OLED this is arguably the best set on the market for 2016
