I'm a consumer like everyone else. My father modeled being thirfty (he saves gift wrapping paper and aluminum foil to save money). We've spoiled our kids, but get them to eat and drink cheaper products as well like Little Debbie snacks or Little Hugs. Mostly, I'm fanatical about turning off lights. My wife soaks dishes rather than run the water too long. I try to run multiple errands at one time to save on gas. And we re-use bags in multiple ways.
