Every so often, a book comes along that is so practical, you can’t help but immediately using its tips to make changes to your life. The new e-book Sustainability Starts at Home: How to Save Money While Saving the Planet by fellow VGN blogger Dawn Gifford is like that. Within moments of finishing the book, I walked around the house and easily implemented a handful of changes that will save me hundreds of dollars each year! I found this book so completely useful, that I decided right then and there that nothing would make me happier than making sure that each and every one of you could get your hands on a copy. So, I asked Dawn if she would give you guys a coupon to use to make the book super affordable, and she did! But first, my review!
