You won't find large shopping centers in Hoi An; there are only a few modern grocery supermarkets. Shopping in Hoi An can be done either at the central market or at the many stalls on the street.
According to experienced travelers, the best shopping in Hoi An is available on Hoang Dieu Street. Here is the city's main market, where you can buy not only clothes and shoes but also find many wholesale stores selling high-end alcoholic beverages at very low prices. In the market itself, you can find very cheap local whisky on sale.
There are no outlet stores in Hoi An, much less near Hoi An. If you are used to wearing exclusive clothes, you can order tailoring from local craftsmen. However, don't get too complacent, as the quality of garments made in the city is poor.
