The main city market runs every day with raw and cooked food, clothes and basic needs.
There is a Thursday afternoon/night market which is very popular with the locals. Taking the blue songthaew out of town from in front of Wat Sothorn, it's about 300-500 metres. You won't see much of the market from the road as it's down a side street to the right. You may see an ornate wood lace carving shop on the right.
