Online auction - choose a jigsaw puzzle to solve

An online auction is an auction which is held over the internet . Online auctions come in many different formats, but most popularly they are ascending English auctions, descending Dutch auctions, first- price sealed-bid, Vickrey auctions, or sometimes even a combination of multiple auctions, taking elements of one and forging them with another. The scope and reach of these auctions have been propelled by the Internet to a level beyond what the initial purveyors had anticipated. This is mainly because online auctions break down and remove the physical limitations of traditional auctions such as geography , presence, time , space , and a small target audience . This influx in reachability has also made it easier to commit unlawful actions within an auction . In 2002, online auctions were projected to account for 30% of all online e-commerce due to the rapid expansion of the popularity of the form of electronic commerce.
