How to show membership posts one blog homepage

Hi there,

I would like my premium posts to show on the homepage, but just not be accessible from the points at which the shortcodes are added.

I have tried selecting and deselecting categories, but at best, the entire posts from speficic categories are not showing on the homepage at all, and I am a little lost about what to do. When I click on the premium category links in my sidebar, whether as admin or a guest, I get an error 404.

Can anyone help?
