First, you'll need to register, if you haven't done so already.
Gather the info you'll need before you prepare your listing:
Your item description
The URL (web site address) for any photos
The category you'll list under
Go to the Sell an Item form, fill in the info, and review your listing. Be sure to check the information carefully, then click on 'Post Item'.
You'll see a confirmation page; jot down the info, such as your item number. This will be helpful if you want to update your listing, and to keep track of your item's status.
When you have a buyer, you will be notified by the email address you registered with. Please contact the buyer(s) within three business days. You'll want to confirm the final cost, including any shipping charges, and tell them where to send payment. When the buyer meets your payment terms, you fulfill your end of the agreement by sending them your item and leaving feedback.
