I think opening a shop can be an agent, which can accumulate experience. But the disadvantage of being an agent is that you can't guarantee the speed and quality of each delivery, and it's easy to have bad reviews. It would be better to purchase the goods yourself. You can control the delivery and quality, but you should consider the cost and pressure when you start to purchase. As long as your cost is ok, I think it's better to purchase the goods by myself.
