Money Saving Mom is one of my favorite web sites. She is funny and practical and offers some great advice. One of the best things she has written is 31 Days to a Better Budget. I highly recommend it. It will only take you about 30 minutes to read through the entire series and she offers great advice like, plan your meals in advance and don't be brand loyal.
While I do disagree with her on the concept of buying the newspaper (come on, a girl's gotta eat!) it is still a great series.
