Need advice…Is there a plugin for this…?

Hi.

I would be grateful if anyone can help me…

I am looking for a plugin or a way to show a certain section of content (not the whole page – I know how to do this) that only appears on a page once you are logged in.

For example a product page that when viewed by the public has no price, but if you were logged in a price would appear.

Can anyone recommend a plugin / fix for this?

Thanks for your support and time in advance.
