Were Kirkland & Ellis clients to go to Office Depot for their printing needs, they’d pay roughly 20% less than what they’re being charged for in-house duplication services at the world’s highest-grossing law firm.

On paper, economies of scale mean that increased levels of production lead to cost savings. But for the service of adding ink and toner to that paper, Kirkland charges clients more than competitors—16 cents per page. Black-and-white copies cost between 10 cents and 15 cents per page at other top Am Law firms and 12 cents at Office Depot, according to a review of bankruptcy court fee applications. At Staples, Kirkland clients would pay a 20% premium per page.
