If I was going to do this kind of thing, which I'm not since none of these grey market items has much appeal to me, I would go online and find a listing of houses which are vacant (foreclosures, or for-sale houses) and use their address. You would not be able to use USPS, though, since those places have their mail stopped. I don't believe this directly violates any laws but IANAL. Alternately, if you were alert enough at your mail fraud you could find a neighbor who is out of the house during the day and use their name and address, and intercept the package from their mailbox. This is, of course, a felony.
