I screwed up today and bought the Logic Express 8 upgrade from my local Apple Store. I got home and, as I usually do, immediately wrote the serial number on the disk with a Sharpie for safekeeping. Then I tried to install it and discovered that I can't upgrade my Logic 7 Academic version. So I now have a disk set I can't return to Apple and can't use. 
If anyone's interested, it's now on eBay:
