Manage Showcase Features   

To manage the features you use on your showcase you use the "Manage Features" tab on the Manage Showcase administration page.

You can use the checkboxes to add or remove features from your showcase. If you are choosing to add a feature that you must purchase before using then click on the "Buy" link beside the checkbox. This will bring you to the purchase wizard. Note that some features allow you to buy more than one of the feature (for example "Real Estate Listings").
