silk bazaar
There is also a silk bazaar near Chahar Su and the Friday Mosque, where you can watch the weavers at their looms and bargain on scarves and cloth.
antique shops
There are several antique shops on the north side of the mosque that sell jewelry, tea pots, old coins, traditional clothing, etc. Be sure and look for Sultan Hamidi 0774282153 in particular - he will happily show off his photograph in the Lonely Planet guidebook, demonstrate any instruments he has for sale, and send you down the block to visit the glassblowers' workshop where many of his wares are made. Bargain hard and in Afghanis!
Money
money changers
There are money changers near Chowk Gulha and along Bagh-e Azadi, north of the old city.
