The first “wild” copy of Mastering Civil 3D 2008 has been spotted- on my doorstep. I noticed that Barnes and Noble was claiming they could ship the text in 24 hours while Amazon appears to be struggling to keep it in stock. Being the geek that I am, I ordered a copy to see if they were serious. The book arrived 48 hours later.
Barnes and Noble is a little more expensive than Amazon for this title, but it includes free 2-day shipping. If you are dying to get your hands on a copy, try them. Also look on Overstock.com.
