There aren't any specific prices of public transport. Just don't forget to bargain they generally charge a high price that you don't wanna pay!! Also taxi drivers and Tuktuk drivers offer a day tour where they say that they will take you to the best attractions of the city, DO NOT GO WITH THEM. They take you to a few places and later take you for shopping where things are expensive as hell and force you to buy as they get commission. If you don't they force you to pay money even without buying!!
So beware! Also since I have been to Thailand, I have posted a few blogs regarding the same so do check them out!! Happy Traveling!
