Amazon is known for its bargains, but did you know you can also use the site to fritter away colossal amounts of money? Of course you did. But do you have any idea how much money? We went through each of Amazon's departments looking for the most expensive item, and what we found was surprising. While there were some objects of genuine value, we found many others that were absurdly overpriced, with sellers often charging millions – or even trillions – of dollars for everyday products. Some of these prices are surely inadvertent. Maybe someone accidentally keyed an inventory code into the price field, or maybe they forgot to convert the currency from rupees. Perhaps others are simply attempts by the retailer to better understand Amazon's search algorithm. And just maybe a few of them are people with dreams of striking it rich. It is, after all, a free country. Note that this 26-item list was compiled in December 2011, and that Amazon's inventory changes quickly. To see what are currently the most expensive items on Amazon's, simply visit one of Amazon's departments and sort the items by "Price: High to Low." You'll probably want to disable one-click shopping first, just in case.
