Fry's has King Kong and Assassins Creed in 4K for $9.99, after using todays promo code. Free shipping starts at $35 dollars, but sometimes you can be a few cents under and still get free shipping. All of the Fast and the Furious movies in 4K are $15, so I got the two $10 movies below and the newest FF movie for $15 and was able to get free shipping that way.
Assassin's Creed [4K UHD] [Blu-Ray] [Digital HD]
King Kong (Ultimate Edition) [4K UHD] [Blu-Ray] [Digital HD] - $9.99
