How to Screw the Post Office

First of all I think the first person to comment must be the author because this book is so not worth it. I only purchased this book for knowledge, I work for the post office. This book was written yrs ago and the things that apply to it don't really work so well today. The whole book could have been summed up with "just reuse a stamp if you can" sure you can get away with it here and there. In one instance the author tells you to place tape over stamp to hold in place. Well I've been working for the post office for 12yrs and have never seen a stamp with tape over it make it through. Nor have I ever seen half a stamp get through the system. There are loopholes but this author obviously is oblivious to them. If you want to save money don't buy this book.
