I just bought a 2nd copy of FCS2. I hadn’t opened the box. They said there is a 14 day return for full refund for unopened boxes. So, I just made the 14 day cut-off and they’ve given me a $500 refund, and I then bought FCS3 for $269.00 direct from Apple (using my Apple business discount). As for opened versions, not sure. They have done a 30 day discount for other software in the past though.
