Jack's of Fiji on Main Street is the polished, fixed-price handicraft store at the centre of town — useful if you do not want to haggle and worth knowing about as a price benchmark. Bula shirts, sulu (wrap skirts), woven baskets, masi cloth, and souvenir kava bowls are all here, of better-than-average quality and at predictable prices.
For a more authentic shopping experience, head to the upstairs section of the Nadi Produce Market, where the same kinds of things sell for less but the quality varies more.
