Some people order seeds online but I believe most grow bag seeds. I don't think you should worry much if you like doing illegal things . On a diffferent site, the one guy got his seeds taken by customs and all they did was send him a letter that buying Cannabis seeds is illegal in the US and no one showed up to his house kicking the door down and taking his plants. He just re-order and got his seeds . If you are scared of get a letter from customs, then grow bag seeds ...
