Sounds quite unlikely that this thieving postman could have intercepted each and every card.
Guys, I'm at the edge of my seat with regard to this thread. I haven't bought anything from this guy, but I very well could have.. I've done something like 10 Amiga deals over the Internet in the last six months, and all deals with ebay and amibench sellers/buyers have gone smoothly like scrolling in an Amiga platformer. Companies have been a bit slow, but have delivered in the end.
If this guy's crooked (I sure hope not!), it means he's purposefully targeting the community because trust is generally high among Amiga users.
