Ebay is supposed to prevent things like what could be happening. One hundred of us buy them for $12.99 and the he runs off with $1300 minus the ebay fee. This is the typical scam,but ebay protects us and is backed-up by paypal. There might be a clause where we lose our money, usually is, but what the hell, if the guy wants to throw away his business, credit, etc for $1300, I guess we have to help him. Or there could be, "...so sorry, lost in mail."
I've also had two or three of the Asian sellers try to invoice me after the fact for terms not in the agreement. The funny thing is though, I have found most of those high-volume guys to be very, very protective of the rep.
Anyway, it won't be the last time I was scammed. But if you think about it, it is a hell of a lot easier to sell a few nonexistent scopes than 100 meters.
