http://costcocouple.com/enjoy-cooking-the-costco-way-2013/ These aren't the best pictures but the only reference I could find to it. I came home the other day and noticed on the table this wonderful cookbook.
Turns out Costco gives them away as people leave the store. Pictures don't really do it justice but it is an absolute beautiful book. A cookbook done right, in my opinion.
Done well enough for me to take notice and even more surprised when I learned where it was from and that it was free.
