If you go to your Purchase History page and select View Order Details for one of your transactions, there should be a line with an Estimated Delivery date and a link for "Show shipping Details". If the seller has uploaded tracking information, clicking on that "Show shipping Details" link should reveal it. Sellers are not required to post tracking info, but it is in their best interest to do so.
If the last estimated delivery date passes without delivery, and there is no delivery shown by the tracking information (or tracking shows delivery to a different zip code), you have 30 days to start an Item Not Received case in the Resolution Center (link at the bottom of most pages).
