Query: where is it ???

Amazon offered this book for purchase over a year ago. i ordered at that time and have been put off several different times. although Amazon isnot responsible for publishing the book they are responsible for makingit available for sale to the public without having to revise the shipping date over and over. Amazon needs to develope better communications with the sellers it deals with otherwise customers such as myself will lose confidence.
