Even though Universal accepts opened F&F returns from stores, the stores still have their own return policies and are unlikely to change them. Plus, the retail jockeys are unlikely to have read any relevant corporate e-mails.
I really think i'm going to try to do this, though. If i'm successful i'll try to convince my friends to do it as well. I'll just have to find the right store to do it at.
P.S. -- in case anyone else is planning on doing this, here's the 'grand list' of copy-protected cds.
