Below the members' part, add a note for everyone else, with the price and a link to the product page. Enable the Content - PaddleSubs Price and Content - PaddleSubs Link plugins, then write:

{paddlesubs !gold-membership}
<p>Read the full guide with a Gold Membership, from {psprice gold-membership} a year.
<a href="/{pslink gold-membership}">Join now</a></p>
{/paddlesubs}

The ! means “doesn't have”, so this part shows only to visitors who aren't members. {psprice gold-membership} becomes the yearly price, in the visitor's currency, and {pslink gold-membership} becomes the address of the Join page. Use {pspricerecurring gold-membership} for the monthly price instead.
