Okay, please bear with me. I’m new to all of this. What if someone were to sell the packaging box online and included cookies for “free”? Then wouldn’t it be like just mailing cookies to your college student or military person? Could that be legal?
It would not be legal. Aside from the fact that your box sale likely wouldn’t sell well without the cookies (the box is not really what you’re selling), typically food laws place the same requirements on publicly-available foods, regardless of whether there is a charge for them or not.
