Amazon has in fact the same system as ebay, they only charge however higer sellingfees, 15% ...However with amazon its possible to let them handle the whole saleprocess, by sending them the articles. If you sell something, and the customer pays, they first block the money till the article is really delivered with the customer (they send the article to the customer). There are also seperate firms that do this processing for ebayers. My formeraccountmanager from ebay started such a company in Berlin, germany. They take over the complete customerprocess, so sending the items and answering questions/complaints. So its in fact some kind of outsourcing.
