Whether or not you’re looking for name brand purses, dvds, or French wine, all these can be bought for cheap in markets within Vietnam. Vietnam is also a producer of knock off goods and although they aren’t as large of a producer (only 1/60 compared to China’s market) it is predicted to grow even bigger. A reason why so many counterfeit goods go undetected is because producers usually import materials and assemble within Vietnam.
The Ben Thanh Market in Ho Chi Minh is a hot spot for knock off goods.
Looks legit to me.
Regardless if you get the real thing or knock off items, make sure you have enough luggage space for it!
