Thanks, that's a good point, and I hadn't thought of that.
This happened on the 2nd. I got the delivered email, but there was no package. I called UPS, got sent to international department, and they said a whole trailer got delivered to the Amazon book return facility here by mistake, and eventually the package would get to me. So I saw it today and was like "cool, it's here" but then I picked it up and was like "Damn."
So somewhere along the line, either at the Amazon place or the UPS guy, someone took the ID box out and taped it up, since no one snuck onto my porch and cut it open and taped it. If it happened on my porch they woulda just ran off with the box...
