Deceit at Amazon

I received an email today from Amazon. The usual occasional offering of a book by someone whom I had previously purchased. This is usually a good service. last week, I found out William Goldman has a new book coming out August 7th. Today's email was for a new book by Billy Collins. At least it appeared to be that according to the email (a screen shot of part of the copy is shown): When I followed the link to Amazon to view the book in details, I found out that Billy Collins wrote the Introduction and was not the author. Is this just sloppy on Amazon's part or has someone else seen examples of this deceit? I am curious.
