Tradera sells goods with bidding or a fixed price. At auction; which is the most popular listing format, it is important to have the highest bid when the time runs out. Really exciting! If the auction has a Buy Now price, you can also buy it directly. A tip is to place a 'Max Bid', ie the highest amount you can think of paying for the item. Tradera bids and then handle the bidding (but never higher than your maximum bid), so you can spend time on other things.
