Best way to send/order Mag pack. Best OPSEC. Money transferring. Best ways to stay as safe. And avoid the Law.

Is there a place to learn about the best way to avoid any legal issues when ordering mags and what not. What how to stay as safe as possible and under the radar. Would like to order to a place that's is not my home with an alias but I head that can be bad opsec. Any suggestions. How likely is it to get busted or caught up in something for something small like. (Personal use) would love a break down of how to do things the right way where as to not have to worry about anything. Getting ripped off is better than getting in some type of legal trouble... technically anyone can send a pack to anyone's place without their knowledge but how would you go about ordering mags and with very little to NO worries?? VPNs, cold wallets not linked to anything. A second phone or computer for ordering only? Using alias. Sending to an old abandoned place... stuff like that.
