Fair warning: Book Depository has cancelled a bunch of orders I've placed in the past due to no actual stock, had numerous shipping issues with them, and they typically don't package their books well at all. (Which is surprising, since it's traveling overseas.)
I only import books from them when absolutely necessary now. While this might be that scenario for some, just be aware.
Out of stock now. But I took a chance and ordered. Will update here if they cancel or fulfill. The fact that it is OOS can mean they accurately track stock, or else just realized their error and pulled it manually.
