This may be old news, but the thing that is interesting is that a minor is running the business (at least that's what I got out of seeing an interview with her), and when I took business law, one of the topics was contracts and minors (under 18 years of age in the US). Minors are not obligated to uphold binding contracts. The example the professor used whas if you sold a car to a minor, he crashed it, he could legally return it, demand a full refund and you would have to legally comply.
A little search found something on the web to corroborate:
