Make sure to use the appropriate keywords to describe the item because this is the only way bidders will be able to find it. Hints for buyers. Watch the bidding on some items you're interested in. Then start off by buying something small. And don't overpay.
Most auctions last a three days to a week.
Use that time to learn about the goods by checking sales prices on the auction sites, local retailers or used-goods stores. If you don't like what you get, find out if you can return it. And find out who pays the shipping, which can be costly on big items. You can also e-mail the seller with any questions you have. Avoid bidding wars.
