I got this book, despite the high price, because I needed to write some copy and was trying to get some good advice. The book is well organized and has lots of examples. The negative is that some of the sections probably won't be good examples to each reader so that even though something here will be helpful, not all of it will, but you still have to pay for it all. The other problem is that most of it is geared towards the big players, those with national scope and budgets.
I don't necessarily regret getting this however, because the cost, if you consider the cost of taking a class, isn't really that bad, the book has value and I did learn some new things. I'd also recommend Sugarman's book on copy writing, he doesn't get as much into layout as this one does, but he really gets into the nuts and bolts of writing stories as copy and compelling people to act. This book is less of a "how to" course and more of a "here it is" now go and do likewise course.
Hatch has spent years collecting and organizing mass mailings and here he presents the best of the best and gives advice on how to use some of this information in your own campaigns. Highly recommend to people in the field or people that want to learn.
