Wonderment there have been no charges for literature anywhere since 2000 at the latest.
I wonder about some of the obscure language releases too. I wonder how many copies of the 2013 NWT have actually been printed in Gun, Ewe and Amharic, for example. Probably some Bibles have been printed in these obscure languages, but perhaps not promoted for general circulation. Even in English the Bibles are not as ubiquitous as they used to be. There is definite pressure to use all literature online rather than print copies, including the Bible.
If their financial position is as bad as I suspect it is they may not be able to afford to print more Bibles in other languages, or even in English.
