So apparently today if you try to buy "Acoustic Kitty" from Amazon or Barnes & Noble (or, essentially, anyplace except Booklocker.com), the site will show the book as being out of stock. This is a dirty, filthy lie. The book is a publish-on-demand book; nobody ever actually has it in stock. You order it, Booklocker prints it, sends it to Amazon or B&N, and Amazon or B&N sends it to you.
The Booklocker folks tell me that this is a database error on the part of the middleman who provides the bookselling services to other online stores. They're looking into it, but as of 4:06 p.m. today, the problem still exists.
Bottom line, if you want the book quickly, order from Booklocker. If you don't mind waiting in the hope of taking advantage of Amazon's "free shipping over $25" dealio, then maybe try back tomorrow. Sorry, kids. Sometimes the computers is stupid.
