B&N's idea of "not-carrying" a book is limited to their B&M storefronts. They do carry them online and they *will* special order them in the stores.
Just like you could do it at home from Amazon.com. (Only not as cheap as Amazon.)
In other words, the one way they could actually offer a service Amazon doesn't is the one way they refuse to sell it. And they make sure everybody knows it, too.
