Interesting pricing at Staples

This pricing scheme at Staples turns the traditional volume discount on its head. Instead of "Buy two get one free," we have here "buy two and pay six times as much if you want a third one."

I think this is a smarter promotion than the traditional loss leader of "Limited one per customer," because here we have a direct comparison to an anchor price. But unlike a regular sale (buy all you want for $1 each while supplies last), there is implicit scarcity (you can only get two.)

I wonder if more retailers will adopt this idea - Staples is the first place I've seen it used.
