when people take a vacation in thailand , one of thr best things to do is to shop.If you want to get a reasonable price , you need to know now to bargain . To start with , try to get the vendor to knock down the price by ten to forty percent . In areas with more tourists , vendors may reduce the price by up to eighty percent . When bargaining , always be patient and friendly . If you offer a price and the vendor accepts , you are then expected to buy the object . not doing so is seen as breaking a promise and will make the vendor upset . Once you get the hang of bargaining , you may find it quite enjoyable .
