@viasindios87,
I am assuming that you are 17 and that '27' is a typo.
As Roger has already said, chances are that when you submitted the order form you had to click on somethin g which said you certify that you are of legal age to purchase tobacco in Massachusetts. This is to protect them, the sellers; they can say they sold you the product in good faith with a clear conscience. You, on the other hand, are guilty of making a false statement in order to gain an advantage.
Can you get in trouble? In theory, yes. But as a practical matter, who the hell is going to investigate to see whether or not you're lying? The beauty of the internet is that we're all anonymous, I, for example, am a six-year-old girl, just learning how too type.
