This is the strangest site. I have never bought from here so I cannot vouch for their service. But they sell cheap generic paper for Filofaxes as well as replacement ring mechanisms for Mulberry and Filofax binders. Not sure how they work or how easy the rings are to replace but if you do have a beloved binder which urgently needs new rings, it would be worth giving this a shot.
