Query: Buy Another Book

Don't waste your time and money buying this book. It is seriously out of date. Many of the companies listed have moved or gone out of business. She has tear-out postcards for mailing to list distributors or consumer databases. I had to double check every address on the internet, and many had changed. The best internet source for up-to-date business addresses seems to be the Better Business Bureau (BBB).I thought this book would tell you the inner workings of the consumer mailing list industry, but all she says is that there are 50,000 different mailing lists out there, and you can get off of some of them by sending out the postcards attached in the book.Buy another book instead of this one.
