Well, I've committed to participating in a challenge to buy nothing new for the entire month of April. Basically, participants agree to buy only food and medication, and I suppose gas for the car. I think it will be interesting to see how we do. We're pretty frugal, but I know giving up eating out will be hard, because we've fallen into that habit since the kids have grown up.
Wish me luck! I'll keep you updated on how we do.
