This is a local story from a friend in the know, so you can at least be assured that it's true. I am posting this just as a cautionary tale.
A couple in Dumaguete was offering their lot for sale. A potential buyer approached them, Arab financier in tow, claiming they were interested in buying. In the course of their conversation, the potential buyers let drop that they were looking for suppliers for a particular chemical of which a Malaysian producer had a monopoly.
Coincidentally, the couple also gets a call from someone purporting to sell said chemical. The seller was in a rush to dispose of his supply because of some financial emergency. He would give the couple his stock, even for just a downpayment.
I guess you can already tell where this story is heading: The couple bought the stock, and the buyers disappeared, leaving them with boxes of chemicals that they don't know what to do with.
I don't know how I might have fared under a similar situation. Perhaps they were blinded by the prospect of an easy sale, and additionally misdirected with the promise of the purchase of their lot. But I guess the moral of the story is: one should not be too eager in these transactions.
Take care now, y'all.
