For shopping areas in Rome see Shopping Streets
Most shops follow normal business hours and open at 8–9am, shut for lunch until 3–4pm, and close around 6–8pm. In tourist areas and at larger stores, the lunch break (riposo) is slowly disappearing in favour of orario continuato (open all day).
Expected in markets (see Top 10 Markets), but hardly ever in shops. Many market stall-holders now hail from Middle Eastern countries where bargaining is an art form, so be ready to do the full ritual, including acting less and less interested, while the merchant acts ever more offended and claims he can go no lower. He will not sell it for less than a profit, so any price agreed upon is acceptable.
