The WTS would have to put up a lot of money upfront for this seeming demand for new Bibles, paper, ink, durable cover quality.
Does the WTS have such funds to put upfront?, then they would have to be concerned about the pubs. actually paying for the value+ asap. Then, their people might not have a clue to how much they should donate and therefore a 'hat dance' or 'guessing game.'
