This is a sample page created as an example of a URL that can be used with the DotNetNuke subscriptions module.
When a user is taken to the PayPal subscriptions page, and asked to pay for they subscription, they have an option to not pay and cancel the transaction at that point. When that happens they will be taken back to the URL configured in the module under the Cancel URL.
This page could offer support or assistance for the sales process or simply a message advising the users that they have not been charged.
