I second this. I feel silly paying for it, but if you (and your spouse, if applicable) totally buy into their system, it’s a way of life. The biggest thing is how it sets up purposeful sinking funds (instead of just “savings”) - every dollar has a job. Now when we have major expenses, it’s like - meh! Water heater went out? No sweat, home maintenace got you covered. And if it doesn’t, you roll with the punches and transfer it from some other category.
It’s made finances so much less stressful.
The slinky my middle child got didn’t even survive the day.
Has anyone had a slinky that survived more than a week?
