The Efke 100 for sale by J&C is expired (9/05), and the fresh stuff is going for almost 40 bucks more than the guy is asking for his Bergger on eBay.
That said, these guys are, ummmm... poor businessmen. A guy you don't know from a hole in the wall walks into your shop, and asks you to order him something you probably can't sell to anyone else, and you don't get him to pay full price up-front. That's pretty dumb, don'tcha think?
