Large international companies, such as IBM, sell their newest products and offer services on eBay using competitive auctions and fixed-priced storefronts. Separate eBay sites such as eBay US and eBay UK allow the users to trade using the local currency. Software developers can create applications that integrate with eBay through the eBay API by joining the eBay Developers Program.[105] In June 2005, there were more than 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.
