Making a listing on eBay permanent?

[Connor]

How do I make a buy it now listing for longer than 30 days? I've seen some things on eBay which have never ended, but I can only list mine for a maximum of 30 days.. Can I make my listing permanent? it would really help thanks

"Duration
You can list for 3, 5, 7, 10, or 30 days, or Good 'Til Cancelled. Good 'Til Cancelled listings renew automatically every 30 days until all of the items sell, you end the listing, or we end your listing."

I believe this must be under a fixed price listing and not an auction.
