Which programs can I still buy to keep?

Hello!

I'm a bit confused by all the new programs included with FB Plus. It says in descriptions that you need either an active membership (which I don't have) or you have to buy a pass for the duration of the program. Once the membership or the pass expire, the program is no longer available to you.

Which ones of the newer programs can still be bought once and for all, like it used to be? There should be a symbol to indicate them, so a potential buyer doesn't have to read all the descriptions and it's clearer.

Thank you to anyone who can help!
