That's kind of like my situation. Even though I bought a lot of 3.5 books, our group never updated our core books. (Indeed, at the time, we kind of resented doing so.)
Nevertheless, our group wants to update to 3.5 now. I've bought the DMG and MM for reasonable prices but the PHB is hard to find cheap. And it doesn't help the situation that I need to buy multiple copies!
PM Ktulu and the other people who have made kind offers in this thread. Find out how much each of them will charge to unload their PHs and the shipping charges to your location. Be sure to post to this thread with the results since there are probably other people in your situation who would love to pick up any additional PHs you do not want.
