Hi, Lacey,
I've been lucky. There have only been a handful of occasions on which I haven't received the items for which I paid. The sellers are overseas, otherwise (of course) I'd have put on my dark glasses, driven next to them, had them plucked off the street by one of my minions, greeted them with a cold smile, and said something like, "Hello, boys. It seems we're going to get to know each other a whole - lot - better. Drive to the Interrogation Cellar, Hubert" (Hubert would be the driver) - and then - then - had something incredibly merciless done to them.
But most of my sellers have been fantastic.
