Stores and other businesses in the downtown area generally stay open from 10:00am until 9:00pm.  In some neighborhoods you may find that they close for two or three hours for lunch. Other shopping opportunities can be found in one of the many malls all over Amman; and usually you will find smaller shops near the place where you live.  There are also a number of more traditional souqs around the city.  In general, many items are more expensive in Jordan because of high taxes and because many things are imported. Second hand goods, however, are much cheaper than in the US.
