So, I did something that I should have done right from the start. I checked out my artwork on FineArtAmerica.com to see what the customers are paying. I have set amounts that I receive per print size and FineArtAmerica.com adds printing fees, framing costs, etc.
I have fixed all of the prices to a much more reasonable amount, and have set my default prices to these new prices. Check out my profile at http://fineartamerica.com/profiles/carolyn-bueckert.html
