Removing prices from website

I am having a hard time removing prices from my website. First off I did not build the website and am unable to contact the person who did so. That being said I want the prices removed from the store and have tried several ways of doing so. If someone could please take a look at the website and try to help me out. I need very easy basic instructions if possible since I don’t know web that well. Which folder or page do i need to go to to remove it? Anything right now will help me out. Thank you.
