Why do you think Apple runs their stores at a loss? In 2012, they were nearly double the profit/square foot that Tiffany's had (I haven't found more recent data on the profit/sq.ft metric) at around $6,000/square foot. In Q1 2013, they were well over $10 million (closer to 15) in average revenue per store.
