"America's Cheapest Family Gets You Right on the Money" by Steve and Annette Economides "puts meeting your financial goals - and living well at the same time - in reach for every family."
The family also has a website available: http://www.americascheapestfamily.com/.
I just began reading it, so I haven't gotten very far into it. But, so far, I am loving it and really excited to put some of their ideas into practice!
I believe that the book is also available as an eBook.
The best part is that I got this book totally FREE, including shipping! (and Amazon's price is already well below the list price!)
How? By using Swagbucks to earn digital dollars just for searching the web. I use these dollars to cash in for great prizes, including Amazon gift cards! And shipping is free with Amazon Prime, a subscription service that you can try free for 3 months. Just be sure and log in to your Amazon account and cancel the service after you receive your first order. It will not actually cancel until the 3 month trial has ended.
Not familiar with Swagbucks? You can read this post to learn more and you can sign up at the bottom of the widget on the sidebar.
