I came here to say that precisely one month ago, this post inspired me to stop wishing we didn't spend so much on groceries/dining out, and start cooking more at home.
30 days later, I'm happy to report that we spent $350 less in October than our average month, and our grocery spend was the exact same. That's right, we ate at home more, spent the same on groceries, and saved $350 in one month. Incredible.
Thanks for the inspiration!
