AstroPhilosopher writes "The U.S. Supreme Court will hear an appeal from a Thai student who was fined $600,000 for re-selling textbooks. Trying to make ends meet, the student had family members in Thailand mail him textbooks that were made and purchased abroad, which he then resold in the U.S. It's a method many retailers practice every day. 'Discount sellers like Costco and Target and Internet giants eBay and Amazon help form an estimated $63 billion annual market for goods that are purchased abroad, then imported and resold without the permission of the manufacturer. The U.S.-based sellers, and consumers, benefit from the common practice of manufacturers to price items more cheaply abroad than in the United States. This phenomenon is sometimes called a parallel market or grey market.'"
