This Shenzhen electronics and appliance chain debuts in Beijing with three floors of all imported goodies. Sundan is home to the first open electronic market in the city, so shoppers can try every single gadget in the store. Each floor is clearly marked and products are organized by their function, making Sundance the most navigable electronics store in town. The staff, mostly college students, are helpful and speak English. Prices are fixed so there’s no bargaining. Other services include free delivery, pre-purchasing options and member-card services.
