Dealing with potential clients negotiating over prices or offering to pay in exposure

I started my business in January and the biggest problem I'm consistently having is negotiating my prices. Far too often, a client comes to me expecting me to work for free (or as they like to call it "exposure"), even though my prices are listed on my website. How do I deal with this? Should I change my rates? What's the best way to determine a fair price point? Thanks so much!
