From a reader Clark Howard is personally responsible for saving me $900 through this book and his radio show, all by doing simple stuff. I heard on his show about the Retirement Savings tax credit that I had failed to take in 2002 and probably would have missed this year. I will make sure to claim it this year and file an amended return last year. That was $400 saved. In the book, he also gave me a source (Costco) to shop for auto insurance that will save me $500 a year for slightly better coverage than I have now. I have checked around at many other companys and never found an offer nearly as good.
