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

Online booksellers (or retailers) have a practice whereby they may classify books as “used” and sell them at a discount even if those books have never been purchased or printed. We understand that this practice can be misleading. Online booksellers may start showing “used” copies of your book even just days after your book comes to market. It does not mean that these books have been purchased or printed. This practice by online booksellers may lead authors to have an inaccurate estimation of the sales of their book. If a new book is printed, the author will be compensated accordingly.
