Where to go shopping in Rome?

A good shopping area with good prices and very nice stuff is on Via Tuscolana and Via Appia Nuova. You can go with metro at Piaza Re di Roma Station. The areas around Vatican (like Ottaviano, Via delle Conciliazione, Via Vola di Rienzo) are little bit more expensive because of tourists. Another zone very nice but expensive is Via del Corso which is located between Piazza Venezia and Piazza dell Popolo.
