Reading this thread this morning was like watching a TV show, I couldn't wait to see what was in the box! I was definitely not expecting paper, but it was a good twist.
In all seriousness, this was an eye-opener. I don't sell a lot of things, but one thing I always do when buying/ selling car parts is local pickup. I got scammed on Ebay years ago (out of about $500) and Paypal did not want to help me, so I've strayed away from that.
