The author of a book suggested that another person download a copy of his work. He told the purchaser that the book was not the final edition, but a preview edition. The purchaser understood this. He told the purchaser that the book would take up to 10 days to arrive. He further informed the purchaser that the book cover for the book he purchased was not the same as the latest edition, that the font text size was smaller and a bit difficult to read than the later edition, and so forth. He did this so the purchaser would be forewarned and not be disappointed.
