No one lives their life to a letter of the law, no one.. Period.
Let's get real here, hey "Bob What are you in for?", I killed 50 people, and you "I used a USPS box for something it wasn't intended for"
When you put metal on the curb for the sanitation company to pick up and some scrapper rolls by in their pick up and takes it. (That's Illegal)
When you buy something on ebay or amazon, and you don't pay sales tax on the item, regardless of the state. (That's illegal)
When you sell something on Craigslist, Garage Sales, Flea Market, Ebay and don't report the profit as income (That's Illegal)
When you "Dumpster" dive for boxes and supplies (That's Illegal)
Let's not get on some moral ground of what's legal or not. It's just called a "Loophole" in the system.
You here politicians talking about closing loopholes etc. When you close a loophole, all they do is make it so it's harder to abuse without a penalty and enforce it (if it's worth the $$ enforcing).
Did you know if you get a ticket for going 1- 14 mph over the speed limit, the judge normally frowns upon that? That's why most tickets are written for people going 15 mph or over. (Unless it's a school zone - they become a little stricter their)
Also, to the person that buys the plastic label holders, just walk into fedex, you can get those for free, no need to spend money on it.
Also get yourself an industrial shredder, I got one from a locker, I bought it just for the shredder. Anyway, as we all know their's plenty of papers you can shred in just about every locker to last a long time. If not, just shred all the advertisement mail and newspaper you get.
Like I said, I don't condone anything illegal. I just recognize it as fact and that people do it. You do whatever makes you feel morally special inside. But the original posted wanted to know why shipping kills him and and not others and I answered that question.
