40" Samsung 4K/UHD Smart TV 40MU6290 $298 at Sam's Club or Free Shipping Online
Walked into my local sam's for holiday samples and came out with a 40" 4K Samsung - it was too good to pass up for under $300. It is the MU6290 model which I don't think is as good as the MU6300 model but I don't really care because it was only a 40".
Plus it was cheaper than the 40 Samsung 1080p on the same shelf. Had to pass along the deal. Online says price is through 11/22.
