Haitian's is cheaper than soy sauce, but there should be a difference between each brand. Today in the supermarket I saw Haitian gold standard soy sauce 500ml package is 9.9 yuan, the same capacity package Haitian mushroom soy sauce is 12.9 yuan. It is recommended to go to the regular supermarket to buy, if you do not want to go out you can go to the online supermarket to check the purchase, more convenient.
