It's not written in stone yet, so let me know your thoughts.
Being a second-hand owner, this sounds fair to me. It makes sense. I wouldn't want the original owner of my player to miss out on the discount, but I wouldn't expect Empeg to offer ad infinitum discounts to every subsequent second-hand buyer. One discount per serial number sounds fair, and easy enough to track. I'm guessing you'll put a time limit on the discount offer to prevent long-term confusion.
