Catching up on some stuff in my news reader, I saw a post about the Consumer Action Handbook from the Federal Citizen Information Center. Put out by the Federal government, the intro say:
This everyday guide to being a smart shopper is hot off the press and chocked full of helpful tips about buying a car or home, preventing identity theft, understanding credit,filing a consumer complaint, and much more. In the 2008 edition, you'll find updated information about filing for bankruptcy, finding a lawyer, and planning a funeral, along with many other useful topics.
You can order a printed copy, or download a pdf on the download page.
