Sarah had a random idea that a vending machine would require her kids to pay for their own snacks, which they could only pay for if they completed basically anything she asked of them. “If they want sweets they can do things (chores, school work, etc) to earn money for them,” she added.

But where would one find such a strange purchase? It was actually pretty easy, “got it from Facebook Marketplace,” she said. And then she went out and loaded it up with her family’s favorite goodies.
