I have not always even had my fake ID photocopied at mom and pop places. Go to the poorest area around you and find a mom and pop box place. They have the worst security and follow procedure the worst. Getting a box at PO is the worst option, and UPS store or other chains are a bad idea too. You have to be careful about electronic stake outs as well, they could put GPS devices inside the package. Best practice is to open and inspect the package before ever taking it back to a location linkable to you. Grab the package, put in layered anti static bags or similar to kill any included devices ability to transmit, take it to a random location that is hard to quickly access by car, and quickly check it for tracking devices, ditch the packaging somewhere and then go back to your pad. Make sure not to have a cell phone on you as well. I am a fan of using public transportation as much as possible during the entire process as well, from you to the box to the random location and back to your house.
