A "luxury fair" designed to appeal to the world's richest people took place in Sardinia this past weekend. But if you were thinking the economic downturn would have put a damper on things, well, think again. Thirty bottles of "Exousia Gold Luxury Water," which is describede as a "gold petal designer label mineral water" and costs $2,800 a pop, were sold over the course of two evenings. And the water still isn't good enough to drink as is, apparently. "A spokeswoman for Exousia said sales were mainly to Russians, who 'like to use it to make tea.'" [DJ/Wealth Bulletin]
