I have complete Buffy twice already. A third time would just be redundant. 
Why? Don't you own Smallville three times? Isn't Buffy worth the same? 
I do not own
Smallville three times. I only have 29 seasons of this ten season show (I have season 6 only twice). That makes a coverage of 290%.
I have 15 seasons of
Buffy which is a seven season show. That's a 214% coverage. If I were to buy another complete set, I would have 314% coverage and that would just be ludicrous.
