The Smart Mama is giving away a Wii and a Wii Fit. I would love to have the Wii Fit, because I have heard so many good things about it. It would also alleviate the embarrassment at the gym. All you have to do to enter is leave a comment with a green, organic, or non toxic tip.
Mine was that I buy the Arizona Green Tea in the gallon and then I put some in my leftover individual water bottles. It's cheaper than buying the individual bottles of green tea and makes me feel better about reusing the bottles. For the gallon container, I save about 10 of those each year and then fill them with water at the beginning of hurricane season.
