I did the shirt once, too. I also went no stealth once, too. The package said, "wallet," even though there wasn't a wallet included and I didn't ask them to do that. I thought that was mighty cool of them to think ahead like that. They're taking care of their US stoner friends.
Some security thoughts that I go by....might help....might not......I'm careful not to buy too much at one time. Do a couple small orders a few days apart instead of one big order of 500 seeds.
Also, don't have it sent to your house. Find a trusted friend, use their address and a made up recipient name. That way, if they get caught they can claim they have no idea who the package belongs to. Never have your grow stuff sent to your house.
