See if you want to start from scratch or buy a station. A few thousand dollars from scratch is enough. If you buy a station, it depends on the size. For example, a station that wants to buy 500 bottles of milk is about 50,000 yuan. The net profit of a bottle of milk is about L yuan a day, and 500 bottles of milk can earn 500 yuan a day. The big brand will pay 10 thousand yuan to sell you a bottle of milk 100 yuan. A bottle of milk sells for more than 200 in first-tier cities, and it is above 100 below second-tier cities. Drinking milk in rich places is stable, and drinking milk below the second line is unstable. If one person delivers it, 500 bottles will be the top, earning 500 a day.
