How can I upgrade my Ad Package to a different package?
You actually don't upgrade an existing Ad Package. Instead, you use up your current Package and then purchase another package, or a single listing.
Example: you purchased a 3-Ad Package. You listed 2 properties, but now you have 2 more properties to list. What you need to do is to place the 3rd listing remaining in your 3-Ad Package to use it up. After that, you can either purchase another 3-Ad Package, or you can purchase a Single Listing.
You can also purchase a different Ad Package while you still have another Package active. For example, let's say you have a 3-Ad Package. You cannot purchase another 3-Ad Package while the first still has listings available. You can, however, purchase a 6-Ad or 10-Ad Package.
