Quick Summary

An online auction is a method of buying and selling goods through open public bidding on the internet. Websites like eBay host these auctions, allowing people worldwide to bid on items. Bidding typically ends at a scheduled time, with the highest bidder winning. The number of bids often indicates an item's demand. After the auction concludes, the buyer and seller arrange payment and delivery, usually via email. This process has transformed how many goods are sold, making rare or common items accessible to a global audience.1
