From the Homepage, select the “buy or sell” link. You can also bid on any items that you see in the news feed or on profile pages.
Notice the tabs showing “All Items”, “Auctions”, and “Fixed Price Listings (Buy It Now)”. These will help you filter your search. Click the “Auctions” tab. Remember when you make a bid, you are agreeing to either sponsor the item or finalize your purchase if you win, so only bid if you intend to buy.
Click on the item you want to buy. The next screen will show you the description of the product. By clicking on the tabs, you can check the seller’s feedback rating, the shipping details, and other bids. Enter the maximum amount you wish to bid for the product. The system will continue placing bids for you until it reaches you maximum.
You can choose whether you would like to automatically sponsor the listing if you win, and you will receive a notification if you are outbid.
If you win, you will have 72 hours to pay for the item, sponsor it, or make it unpaid.
