I have a very niche book that is primarily sold through Amazon. A pet peeve is always third parties offering "new" copies of the book when I know the only way to get a legit brand spanking new copy, previously unshipped, is via my publisher (me) who uses Ingram/Lightning Source to print and fulfill on demand. Ordering a copy on demand from LS is not possible for the general public. So naively, you should only be able to get "new" using the sold from Amazon* (as they get stock from Ingram periodically) or by my back-stop listing which is out of my own personal inventory. What I've found out since is that some of the resellers are able to order directly from Ingram and so can somewhat legitimately offer a "new" copy for sale through Amazon. Their listing prices are always above the default Amazon price as they need to recover the Amazon selling fee (greater than the 28% wholesale discount I offer through Ingram). Unfortunately, when Amazon's stock is out they frequently list such sellers as the primary seller on the product page (buy now) rather than my own listing (which is in name of the publisher). So if you see a listing of "new" and it is below the official Amazon price, it is not really new. It may be "like new" but it is definitely not new. Those listings at prices higher than Amazon's may, or may not, be new. *Ingram is able to distribute to a long list of booksellers so it is entirely possible a book is printed on demand off an order through say BarnesandNoble.com. While I do not get any info on who Ingram sells to, it is pretty easy to track Amazon's by their references to either how many remain in stock or "more on the way" and a print order hitting Lightning Source.
