An auction is a method of selling goods by asking buyers to offer bids. The highest bidder wins the item. Online auctions are a highly popular way to buy and sell items online. Online auctions such as eBay, eBid, and uBid provide a platform for buyers and sellers to connect and post and bid on auctions.
The boom of online auctions began when eBay gained popularity in the late 1990's. eBay remains the world's most popular marketplace and auction platform.
