I'd clean house and move the computer also. If they come, play dumb. Worst case they do a controlled delivery, storm your house, tear it apart... and find absolutely nothing illegal. Not only that, but this guy doesn't even own a computer to be ordering stuff on. Yea, he's got a package, but had written return to sender on it and hadn't even bothered to open it. Now, how strong of a case does that sound like they have with all that? They probably couldn''t even get the DA to waste his time on it, and a half ass decent lawyer could get you out of it.
Another comment I do wanna make though. I read so many times on here that "unless it's a shitload of gear and you're a big time dealer, they aren't gonna waste their time on you." Bros, I have to tell you differently. I had my house raided twice by customs and local narcotics who were working together. The customs agents came all the way from the state capitol which is three hours away. I had never ordered anything before, had never sold anything to anyone, and didn't even use my home computer to do the order. I was a newb to gear and the source was a terrible mexican supplier whos delivery method was just asking to get busted. However, they saw it fit enough to drive the three hours, notify local authorities and do a controlled delivery on my house. I wasn't here, but the person I live with was. They refused to sign for the package, but the agents already had a warrant regardless of acceptance of the package. They came in, tore the place apart, found one bottle of QV deca with about 3cc's left in it. Came to work and picked me up and spent about 5 hours shaking me down at the local narcotics office. I played like a dumb kid and ended up never having any charges pressed. Never even had to contact a lawyer. But I was lucky. The point is, they still invested all of that manpower and time into what they had. And what did they have? The amount of gear in the package they seized? Two 10cc bottles of prop and 100 10mg winny tabs. That was enough for a federal raid. Just something to keep in mind.
