When reached by phone after many attempts, someone at the Kunming store finally picked up. He said that unlike other black market operations, their faux-pomme shop was above the board, selling only authentic Apple products, at normal Apple prices, to customers who don't have access to one of the only four legit Apple stores in all of China.
And they're not gonna change. At least not for now: "It doesn't make much of a difference for us whether we're authorised or not," explained the clerk. "I just care that what I sell every day are authentic Apple products, and that our customers don't come back to me to complain about the quality of the products." So there you go, Genius. [WSJ]
