Not as disastrous as the other examples here, but this one made it into my home. It's the underside of a Dr. Who, my first (and last) container pin. I had only been given some basic pics of the top side before I made the overseas deal. It looked pretty decent up until then... but when I got it home and lifted the PF, my heart sunk. Lucky for me the seller took it back (in trade for another). Lesson learned. Buy your pins in person.
