The Feria Artesanal Angelmó is wall-to-wall with souvenir stands along Av Angelmó, selling crafts from throughout the country and an amazing amount of stuff (some junk, some decent) from more northerly countries. Also try the labyrinthine waterfront market Pueblito de Melipulli, opposite the bus terminal. For bigger purchases, head to Paseo Costanera.
