I just finished reading Zero Waste Home by Bea Johnson. I really enjoyed it, even though many of her suggestions have already been presented on her blog, of the same name. She was motivated by environmentalism, rather than being frugal, but reports her family's costs substantially decreased with her efforts to generate zero waste. She takes a lively, encouraging tone (much more appealing to me than No Impact Man). One of her key messages is to "refuse" things you do not really want and will end up throwing out -- like the free cheaply made vinyl briefcase at the convention, the free plastic cup and lid for your child at the restaurant chain, the many items you receive in the mail (I am canceling those alumni magazines I never read.) I think many MMM readers would appreciate this book.
