Askinng for 2 credits on a print book is against site rules and can get your account closed. Please read the rules of the Bazaar in the red sticky at the top of this forum:
General Rules in the Book Bazaar:
(4) No asking (or offering) more than "PBS price" for a book. For example, "I will pay 3 credits for this Wish List book" is a violation of this rule, as is "I will send you this book for 3 credits" if the book is worth only one credit on PBS. All bound books "cost" 1 credit each at PBS, and audiobooks "cost" 2 credits each. We don't want a "bidding war" for books, and it is not fair to cut in front of members who may have been waiting for a Wish List book for a long time. That is why offering/asking extra credits is not permitted.
