Ben Thanh market is one of the most popular places to buy souvenirs and anything else that you need or want. The market is visited by many tourists everyday thanks to its central location and the reputation of being an authentic shopping experience.
Although you can find almost anything there, the products are often of low quality, and the vendors are unlikely to haggle. You might be quickly put off by the attitude of some sellers who don't seem to understand the rules of bargaining and act like they don't care if you buy from them. The prices are often even three times higher than what you should pay, and most likely, you can find an identical product in a shop that has a price tag on it.
The market is open every day until late afternoon. In the evening, outside the building the night market appears and offers similar goods. Have fun walking around and absorb the great atmosphere, but don't feel like you are obliged to buy anything.
