Why is the online bookseller (or retailer) selling some of my books as “Used” even just days after my book was published?

Online booksellers have a practice where they may classify books as “used” and sell then at a discount even if those books have never been purchased or printed. This does not mean that these books have been purchased or printed. We understand that this can be misleading and causes authors to have an inaccurate estimate of the sales of their book. If a new book is printed, the author will be compensated accordingly.
