I am graduate student at one of the local Universities in New Jersey. when this book was given as one of the materials that we were going to use throughout the semester, I did not panic until I went to the book store and saw the price. immediately after class, I went to Amazon.com and start my research. It took me approximately 5 minutes before I found the book. the book arrived between 3 to 4 business days in very good condition. the whole process deserve 5 stars.
