Your payment history shows that you paid $4.99 for the starter pack. If you want the full content, it costs $25.
I feel like I told you this a few days ago the button saying 50% off takes you to a page that says explicitly it comes with
-Free version
-Starter pack
-Extra plus version
Nothing there says you need to go to this page specifically to pay the 25 dollars for the full version.
Everything is very well explained in the descriptions of each package.
