How would I have to steal a box? Pick it up, turn it over, there's the number... (Unless the brown cardboardy box came packaged inside another box [I can't remember if i did], which seems like a waste.
Anyway...
Hah... After all this and I'm still screwed. The whole point is that I'm trying to install this older copy on a G3 in the office, but I didn't see a slip of paper inside with what I thought was the serial. Now that I've got that, I tried installing it and it asks me for some sort of verification number instead, which after a bit of looking online IS supposed to be on a card inside the box.
Hmm...
