To promote upcoming releases and encourage pre-orders, publishers will run sweepstakes offers where customers who pre-order the promoted title are automatically entered to win a prize package provided by the publisher.
Prizes vary from signed editions of the book, gift cards to Barnes & Noble and/or other retailers, gift sets, exclusive merchandise related to the book/series, with some even offering trips or cash prizes. Prize packages vary for each offer and some may offer more than others.
