eBay items and services

wikipedia:

Millions of collectibles, appliances, computers, furniture, equipment, vehicles, and other miscellaneous items are listed, bought, and sold daily. Some items are rare and valuable, while many others are dusty gizmos that would have been discarded if not for the thousands of eager bidders worldwide, proving that if one has a big enough market, one will find someone willing to buy anything. Anything can be sold as long as it is not illegal or does not violate the eBay Prohibited and Restricted Items policy. Services and intangibles can be sold too. It is fair to say that eBay has revolutionized the collectibles market by bringing together buyers and sellers internationally in a huge, never-ending yard sale and auction. Large international companies, such as IBM, sell their newest products and offer services on eBay using competitive auctions and fixed-priced storefronts. Regional searches of the database make shipping slightly more rapid or cheaper. Software developers can create applications that integrate with eBay through the eBay API by joining the eBay Developers Program. As of June 2005, there were over 15,000 members in the eBay Developers Program, comprising a broad range of companies creating software applications to support eBay buyers and sellers as well as eBay Affiliates.
