Mar 2, 2013 They aren't really trying to "trick" you, it's just standard procedure to send the letter. Obviously you don't and throw it away. Since when has customs ever sent a "follow up letter"? Never heard of that one. Don't talk to anyone, even on the boards? Yeah ok, you forgot to mention move to Mexico and live in the forest for the next 5 years since we are obviously a little paranoid here. Don't order from overseas again? Why not? Get a different address if you need to but it's not the end of the world. Customs really doesn't care about you or your silly little 5 vials of test you ordered.
