We once tried to get permission to distribute the NKJV but did not receive it. It seems distributing their "Bibles" is not the top priority of Bible publishers.
Furthmore, since Thomas Nelson (and Zondervan) have been acquired by the secular and worldly company Newscorp (run by Rupert Murdock), we will very likely not try again.
Personally, I have found the AKJV and KJ2000 to be superior to the NKJV.
(We do have a personal version of the NKJV that may be in a screenshot)

But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness. (Rom 4:5 AV)
