Can you only show wholesale pricing to logged in customers while displaying descriptions to anyone?

I am developing a wholesale site using the Simplemarket theme. I want to be able to show product descriptions to anyone, but only allow logged in users to see pricing and use the cart functionality. Is there a way to do this on one site, or do I need to use two sites using the privacy plugin for the second site? If I make the second site, is there a way to sync the product database in market press so we don't have to double enter product?
