Well, literary boys and girls, I'm sorry to be the book publicist to break it to you, but...well, there's just not easy way to say this. Amazon and Borders are getting a divorce.
It wasn't anything that you did. In fact, it wasn't about you at all. It was just that Borders needed its own Web site. Sometimes, that happens, even when two companies loved each other once upon a time and cohabitated (or, at least, shared a Web site) for years and years (in this case, seven years).
Borders new Web site, you may not be surprised to learn, is Borders.com/. And Publishers Weekly's story about the Amazon / Borders breakup is right here.
Note that Baker and Taylor is handling fulfillment for Borders.com. Also, whereas Amazon offers free shipping for book orders that total more than $25, Borders lets you pick up orders at your local bricks-and-mortar bookstore for just the price of the gas you'll need to get there. Hmmm....
