We have been doing flour wholesale 16 years, and the grain and oil industry has always had the lowest profit, but there are few opportunities for this industry to lose money, because people have to eat at any age! We wholesale a bag of 50 kg flour around 80 yuan, and the profit of each bag of 2 yuan money feels very profitable. Generally, it is gross profit 1 yuan. If you want to make money, you must rely on volume.
