s2Member Multiple Products Available To Unregistered People

Hello everyone,
I have a question regarding s2Member and I can’t seem to get a proper solution.
I want to have 4-5 different products available to people who are not members but I also want them to be independent (if you purchase one you will not have access to the others).
I could use Custom Capabilities but they require people to already be registered, which I don’t want. Is it possible to make Custom Capabilities available to people who don’t have a member account ?

Thank you for your time and support, it is very appreciated !
