Ordered something from Germany last week. I just received a call from some kind of investigator telling me they found an envelope with drugs in there addressed to my home. They went on their police computer network and somehow found out my cell number. I guess I'm gonna be fine because I didn't use my real name, worst case I gotta pay a fine. Apparently the envelope came by airmail, and they check envelopes at the airport frequently using dogs, or so it seems. I also think it depends on what country you live in. Richer countries spend more resources on looking for drug deliveries.
Bottomline, be careful. I'm gonna order domestic only from now on.
Nobody said they don't check. The thing is that they check the same way they would as if it was a domestic shipping
