Start with the auction in question. Make sure that you read every word of the description and the auction details.

Pay special attention to what the description and auction details do not say. For example, is a guarantee mentioned? Is the item new? Is it authentic? Is there evidence of authenticity? Look for auctions that provide the right information, and just keep away from those that do not.

Who will pay the shipping and handling costs? Often, the buyer pays these costs, but sometimes, the seller tries to charge more than the actual shipping and handling costs are. Be careful of high shipping costs, especially for items that will be auctioned off at a very low price. Note when the item is supposed to ship after the bidding has ended.

Don't make the mistake of bidding on an item merely because it is a 'good deal.' It is only a good deal for you if the item is something that you really want or need. A lot of people simply bid for the sake of bidding - or winning - without having any real need for the item in question. Before bidding on items that you do want or need, it's best to check prices around the Internet and the prices available from offline sources as well.

Learn more about the seller. What is their rating? Read their feedback page. Not learning more about the seller can be very costly. Sometimes scammers make their auctions sound like really great deals. Be cautious of prices that seem to be extremely low.
