What's the worst packaged item you've ever received from eBay?
I bought an autographed Chewbacca Star Wars action figure. The figure was "new on card". I paid $5 for USPS shipping.
When I got the figure, it was in a cheap $1 bubble mailer FOLDED IN HALF. Although I was able to somewhat flatten out the card, pretty much any collector's value it once had is now gone.
