Regarding the selection of goods sold in coffee vending machines, many operators look at what others sell and sell what they sell, such as instant noodles, snacks and drinks. This cannot be said to be wrong, but the consequence of this selection is that your product refurbishment rate is very low and it is difficult to sell the product.
The choice of goods should be determined according to the type of people near your location, not according to your own preferences. For example, you put a lot of instant noodles in a coffee vending machine in a shopping mall, and instant noodles are almost never bought by tourists visiting the mall. Before choosing a product, you should step on a spot near your point in advance, think about what kind of consumer groups the people passing by this point belong to, and what consumer needs are there, and then choose products based on the information obtained. These are the easiest and most important two minefields for novices to get started. Many novices have planted somersaults on these places and left the game in despair, so please remember.
