Lotte has plenty of stock left because local Vietnamese prefer getting their stuffs at smaller neighborhood convenient stores. Also, many do not have the purchasing power to shop at Lotte yet.

There was a documentary on Youtube on the effects of Agent Orange on Vietnamese children. Some are mentally retarded, some born without limbs while others have defective hearts.
