Someone told me the product with best margin that Costco sells is ... Kirkland toilet paper.
They drove down the cost to absolute minimum simply by opening their own factory.

That sounds wrong. Toilet paper isn't a traditionally high margin thing, and I doubt they'd be able to wring out much more margin by buying the factory, or else everyone would do it. High margin products traditionally are either the luxury products, low volume products, or convenient/convenience products (chocolates by the till, sandwiches to go).
Now its possible that toilet roll is their most profitable product in absolute terms. Everyone needs toilet roll so they probably sell a lot.
