5. General Consumer Auctions  One of the most successful consumer auction Web sites is eBay.  The eBay home page includes links to categories of items.  Sellers pay eBay a listing fee and a sliding percentage of the final selling price.  Buyers pay nothing to eBay.  The most common format used on eBay is a computerized version of the English auction.  Another auction type offered by eBay is an increasing-price format for multiple item auctions that eBay calls a Dutch auction.  In either type of eBay auction, bidders must constantly monitor the bidding activity.

8. General Consumer Auctions  Portal sites, such as Yahoo! and Excite, have created auctions.  Amazon.com has also recently expanded its business to include auctions.  Amazon’s ‘Auction Guarantee’ agreed to reimburse any buyer not satisfied with listed merchandise that cost $250 or less.  A third party holds the buyer’s payment until he or she receives and is satisfied with the purchased item.
