I was recently able to get some remaindered copies of Mutual Holdings.
So I now have ample copies available, and you can buy directly from me. I'm selling these at a deep discount, so the price is cheaper than it is at B&N and this price includes first class shipping. The total price is $9.75 for US residents, $11.75 for Canadian and international orders. So if you'd like a copy of the book, but you haven't been able to find it at a B&N near you, you can get it this way.
I can't get the little "buy now" button to work properly inside a post here, but if you're going for the US buying option of $9.75, you can click the little button over on the right that says "buy now".
Alternately, for a Canadian or international order, you can visit my webpage here to order.
You can also find several other options on my site, such as how to purchase it along with discounted, signed copies of 24/7 or Trattoria. Again, those buying options are right here on my website.
