Hide Price from Rich Snippets

Hi my dears,

I am using your plugin and I love it so far but I am facing an issue that most probably I am not the first one to face. Mine is a b2b website and we do corporate products. The pricing space that is on the web we used for our cost price, so it is not meant to be shown at the front. Your plugin helps with that and we have all under RFQ… but Google rich snippets are showing our cost prices though! Is there a way to hide it from them?

Thanks a lot!
