The Join page is designed to only list subscription plans and encourage customers to sign up for a subscription in order to access your content. If you want to display bundles, then you will need to create a custom page with links to each bundle you offer, then use that custom page in your home page CTA links and perhaps link to the custom page in your top navigation/menu.
The Join page is automatically created for your Uscreen site and can be viewed by adding /join to the end of your site URL. The Join page will appear blank at first, but you can populate the page by creating subscriptions and making them Public.
The Join Page is one of the few pages where we don't allow code customization on. This page needs to remain secure for collecting login credentials and payment information so customization is restricted.
To populate the join page:
Navigate to the Subscriptions tab and click Add New.
You can then setup your subscription and when the subscription is made Public it will appear on your join page.
Here's what that looks like for your customers:
