Hibiscus Plaza outside the post office in Georgetown has a wide variety of local arts and crafts including straw hats, baskets, clay goblets and jewellery. On Sundays, the Parika Market, on the west coast of Demerara, sells a variety of goods and is worth a visit. Other shops sell Amerindian bows and arrows, hammocks, pottery and salad bowls. Government-run shops sell magnificent jewellery, utilising local gold, silver, precious and semi-precious stones. Prices are very reasonable for the quality of the goods. It is absolutely essential to ensure that receipts and correct documentation are retained, otherwise visitors may experience difficulty when clearing customs.
