Tourist shops are generally open daily from 10 to 7:30. Many Agra shops sell hand-knotted dhurries and other rugs, jewelry made from precious and semiprecious stones, brass statues, and marble inlays that continue the form and motifs seen in the city's great monuments. Resist drivers and touts who want to take you to places offering special "bargains"; they receive big commissions from shopkeepers, which you pay in the inflated price of the merchandise. Beware, too, of soapstone masquerading as marble: this softer, cheaper stone is a convincing substitute, but you can test it by scraping the item with your fingernail—Indian marble won't scrape. Finally, for what it's worth, local lore has it that miniature replicas of the Taj Mahal bring bad luck.
