First of all, his rent is very expensive for convenience stores in airports or railway stations, because land is scarce and there is a large flow of people here, so his rent will be a great expense for convenience stores in these places. Although there is a large flow of people here, his real sales are not directly proportional to the flow of people, because there are many people who he will not choose to buy things here, so her sales are still very low. In order to increase the overall sales, he will add money to the unit price of some goods. Although it may cost one or two yuan to buy a lighter outside, selling 15 yuan here is to improve the overall profit. Although we see that this commodity is very expensive and has a high profit, if we combine other factors, such as its cost, its profit is not very large.
Therefore, considering some factors, although ordinary lighters cost 15 yuan in airport convenience stores, I don't think it is profiteering, because its overall cost is there. In order to increase the overall sales, he has to work hard on the unit price of some products, because if people need it, they have to buy it. Although the overall flow of people is large, the number of people entering the store is still very small. In order to gain a foothold in this scene and get more profits, he had to do so.
