Well, based on what Tom told me when I was in his shop looking through art, and trying to negotiate prices, he said that it totally depends on the artist. Generally, they are not willing to sell their pages for anything less than the listed price. I think that is particularly true for Stuart Immonen (and if you are talking about a Star Wars page, that is probably the case). As he explained it, the artists are perfectly content to hold onto their pages, rather than sel them at a reduced rate. And I think a guy like Immonen, who has a pretty steady art income, that is probably the case. But, it never hurts to ask.
