Do you really want to buy something? They will really pressure you into buying something (if there are two of you, then two somethings!) Don't expect to walk around and browse by yourself!! While the price is cheap (compared with most countries) expect to pay around 18,000 - 30,000 baht for gold, gemstone and tiny diamonds (1800 baht for silver, cubic zirconia and gemstone)
The tour train was quite interesting!
