AP Plaza is Pudong's biggest "fake market", located underground in Metro Line 2's Science & Technology Museum station. The northern half of AP Plaza, called Xinyang, is a collection of stalls, touts, and greedy salespeople out to rip-off unsuspecting tourists with fake, Fake, FAKE goods of all stripes. As a general rule of thumb, offer 10% of the original asking price, and settle for somewhere between 10% and 30%. Bargain hard, carry cash, and be prepared to walk away from a bunch of stalls before settling on a price.
