Most of them don't. They use a drop, or a combination of other methods. One of which is find a random street person to walk into a UPS store and grab a PO Box and pay for the month. At that point you have an "untraceable" box. When it is time to do the pickup you can do it yourself or pay someone else to do the pickup, choice is yours. I am not a buyer on any of these buy from reading these posts long enough I know of at least 5-6 other methods where you never have to use your own address and as long as you deal in small quantities never get caught.
