That can definitely happen. I've never lost one coming to me. Had a few that I sent out over the years that allegedly never made it to their destination. Strangely one that was supposedly 'lost' turned up on a certain TamiyaClub member's page a short time later. I always prefer to pickup things at the post office or UPS. I don't like things left at my door, because there's nothing to stop some chucklehead kids from grabbing your stuff...Yep I did I won a vintage cox gas VW bug and the package tracked and said it reached my local post office about 5 blocks away from me but the package never got delivered and when tracked it said something like undelivered status unknown.
I was pissed because this was a vintage collectable item...I personally think a worker at the post office seen it mayby with a tear in the box and decided to keep it for himself!:mad
