The price of Laoganma chili sauce is between 11 and 14 yuan. Maybe the profit range pursued by the merchants is different, so the prices are different.
I think many products are cheaper online than in supermarkets because the operating costs are different.
In fact, you can make Lao Gan Ma chili sauce by yourself. I have made several large bottles, and the quality, taste, and appearance are the same. There are recipes and procedures online. There are also raw materials online and in the market. It is very simple. If you like to eat, it is convenient and hygienic to learn to cook it yourself.
