Currency and Currency exchange :
Major currency bills and travellers cheques are cashed easily at hotels, tourist shops, all provincial banks, shopping centres and money changers.Travellers cheques are best changed in banks (you will need your passport). Rates of exchange at banks or authorised money changers are better than those at hotels and department stores.
Any amount of foreign currency may be brought into the country. Visitors may take foreign currency out of Thailand, but no more than the amount stated in the customs declaration made on arrival. Travellers leaving Thailand may take out no more than 50,000 baht per person in Thai currency.
Fixed prices are the norm in department stores, but at most other places bargaining is to be expected. Generally, you can obtain a final figure of between 10-40% lower than the original asking price. Much depends on your skills and the shopkeeper's mood. But remember, Thais appreciate good manners and a sense of humor. With patience and a broad smile, you will not only get a better price, you will also enjoy shopping as an art.
