Adding Sellers to your Favorites list is a quick and easy way to keep track of subscriptions that interest you. Find the listing that you want to add as a Favorite and click the heart icon found under the images section.
Once the heart icon is colored in, that means you have successfully added the listing as a Favorite. You can simply click the heart icon again if you wish to remove the listing from your Favorites.
You can also view all of your Favorites in one place by clicking your name in the top right hand corner (assuming you are already logged in) and then clicking the Favorites link. That will take you to a page that displays all of your Favorited Sellers.
