I have all of my textbooks from the past 4 years. I held onto them for the MCAT. Now, I'm ready to sell. Are there any that might be useful in med school, or should I sell them all? Anybody have any advice as to which seller to use (amazon, ebay, barnes and noble, etc)? Also, I have EK, PR, Kaplan, and AAMC online practice tests. I'm selling these too. Am I allowed to post a link on SDN directing people where to go to buy my books?
