1. Look into virtual offices. They are unregulated, don't request ID in most cases. Also often cheaper to open/close all the time. Much much better than P.O. Boxes. Also the set of virtual offices is infinitely larger than the number of P.O Boxes.2. For the potential of a tracking device in a package. Put your item into a Faraday Bag. Google this to research. It's based on the Faraday Cage discovery, where a container can completely inhibit radio/microwaves etc. You can use your mobile/laptop etc so you know it works. Pop them in and then call the phone or send a msg to the laptop via instant message. Pass the item's package onto somebody else or leave it on a moving vehicle and put the contents of package into a new package you brought along.3. Wear sunglasses (wraparound mirror sunglasses are the best according to the whitepapers) to avoid image recognition systems used with CCTV. Don't use the same mail box service over and over, whether virtual office or P.O box. If your photo is in the local LE database, and they have CCTV stills, you should assume they'll run pattern matching utility. While hardly perfect, it narrows the field and the algorithms get better over time. But a hat + sunglasses baffles any computer or human you met momentarily once (imagine everybody you meet en route is behind some one way mirror staring at a line-up tomorrow. What do they see?). I swear I sometimes don't recognize myself when I take off sunglasses + hat.4. On a operation like this, I wouldn't involve more people than me. I don't understand why people who deal weed simultaneously have the lowest margins and the highest turnover of employees. You're closer to Farmer Bob than Scarface, keep an eye on that bottom line! Assets - Liabilities = Net Profit. I hate making hypothetical profits, don't you? If somebody works for me, they either don't even know they're working for me, or else they are paid a % of my profits on a continual basis. That is the best way to prevent informants. It also keeps a rein on your employment costs, since you really really don't want to give away more capital. Different from throwing cash at the problem.
