Online auctions can bring unexpected circumstances into action. Without knowing it, you may compete against bidders who have strong attachments to a particular item. You may encounter bidders driven by ego or by an urgent need to win a particular item. You may bid against buyers who have money to burn and care little for how they spend it. The online auction world can seem like a chess game played in the dark. But common sense and a few simple strategies are what you need to emerge consistently as a winning bidder.
