How do you buy Character Animator?

I have a free trial of Character Animator, but don't know how to actually buy it.

There is a 'Buy Now' button within the Creative Cloud App, but when I click it Character Animator isn't listed in the products on the resulting web page: "https://www.adobe.com/uk/creativecloud/plans.html?plan=individual&sdid=KPGPI&product=Creative%20Cloud%20Desktop&mv=product&mv2=accc".

Nor is it listed here: https://www.adobe.com/uk/creativecloud/plans.html

It is here: https://www.adobe.com/uk/creativecloud/catalog/desktop.html, but that just allows me to download the free trial, which I already have.

I'd be very grateful if someone could help me out.

Thanks.
