You know the saying "reduce, reuse, recycle"? There's not much that is more frugal than that! Here's a good way of reducing trash AND reducing what you spend on new things:
My friend Rachel (hi Rachel!) was reading my blog and she said "Don't open your Pedi Egg, I have extra ones." Since she has a baby, I offered to trade her some of my little one's outgrown clothes for the PediEgg, and I returned the one I bought to CVS, and I got 10.51 back, which I spent on 2 bags of organic potting soil for the garden. Cost: $0 and no negative impact on the environment.
Happy Earth Day!
