Hmm. The seller posts worldwide. Check in on the sellers feedback in a few weeks time. If you're lucky the buyers ID will lead you to some clues about their location.
It is also worth mentioning that prices for these cameras do vary depending on where you want to buy them. They seem to change hands more cheaply in USA than they do in Australia for instance. I'm not sure why this is. Maybe they are more widely available in the US?
I've bought two of them ex-ebay and paid between $80-115 for them IIRC. The more expensive one was nearly mint, if not mint, though. They are occasionally found more cheaply down under but not so often. When you do the sums, even at those prices, local postage is so much cheaper than acquiring a less expensive camera from overseas you may as well buy local anyway, instead of getting killed by US sellers postage.
I did find one at a local market late last year for a great price, from a guy who usually has three or four film cameras on hand; unfortunately, the viewfinder, normally so bright and excellent in an S2, was clouded up with what looked like fungus so I passed on that one. It seems cameras can be more expensive generally here though, so read into that what you will.
