Some of you have commented that you don't own the Tightwad Gazette books. If you can't borrow the first book from the library or can't borrow a book from someone, I recommend that you follow the posts for the month of March without worrying about reading the book.
The Tightwad Gazette books were published between 1992 and 1996. There is a lot of great tips in these books but the majority of them came prior to the highspread use of the internet. Some of the tips may be a little outdated such as saving on the price of postage for mailing a letter. However, the majority of the tips are still great.
All three Tightwad Gazette books have been consolidated into one large volume but it is my understanding from other reviews that it doesn't have all of the information from all three books in it.
If you can find these books used and really cheap, then I would purchase them. At Amazon you can get all three books, used, and at reasonable prices plus shipping. Make sure wherever you order the first Tightwad Gazette book that you check to make sure you are getting the first volume. The first volume has the copyright date of 1992 with ISBN 0-679-74388-X.
If you are uncertain about purchasing these books, then don't. Wait until you have reviewed the posts and comments for several weeks to see if you will really be interested in owning these books.
