I'm not completely sure if the package has a return address. I send my seeds to a trusted friend and pick them up whenever they arrive (he opens the package to see what strains I get, so I don't get the original box it comes in). I was also worried about the feds showing up at my door, but I hear if they find out what's in your package you only get a letter from homeland security saying illegal items were being sent to your house and that they took care of it for you.
