Are items on ebay used & how dose ebay work?

It's not a dumb question. It's sometimes difficult to tell whether an item is used or not. Some items are used, some are refurbished, and some are brand new. Usually, this is specified on the auction page. Sometimes, however, people will lie about this, hoping that the buyer either does not notice or care. Ebay works in much the same way as a traditional auction does. Items are put up for auction, sometimes with a "reserve price". If the reserve price is not met by the end of the auction, the item is not sold. Users bid on the item during the auction. They enter the maximum amount that they are willing to pay on the site. If another bidder enters a higher amount, they are outbid. They can then outbid the person who outbid them though. It can go back and forth like this rather quickly, so some people use automatic bidding scripts so that they can enter a higher amount when there are only several seconds left in the auction. The winning bidder pays the seller according to the terms described on the auction description page. The seller then sends the item to the buyer.
