Biblio is a marketplace site, meaning we display the listings of thousands of independent booksellers. Since our sellers tend to specialize in used, rare, and out of print books, some items are in limited supply. Some of these sellers also have open storefronts as well as their online shops to maintain.
While the vast majority of Biblio booksellers maintain overall fulfillment rates of well over 90%, inventory errors are sometimes an inevitable situation. We'll be sure that you are promptly refunded and notified about the canceled book.
Whenever a book order is rejected you may always search for another available copy from other Biblio booksellers.
