Negotiating Merit Aid?

<p>I just got a letter in the mail that I received a Michigan Excellence scholarship, (40k over 4 years, for out of state students I think). This is thrilling news and would take a large chunk of the burden off of going to UMich OOS. </p>

<p>However, this still puts tuition at about 23k a year. If I could get to the point of paying only 15-20k a year, I would go in a heartbeat. </p>

<p>Is it heard of to try and negotiate merit aid from the University of Michigan? Has anybody had any success?</p>
