1. An agent is someone who helps others sell things and earns the difference. You should be cautious when acting as an agent for others and pay attention to the cost-effectiveness, because you are responsible for the things you sell. If others buy things from you that are not good, they will look for you instead of your supplier~! 2. You need to negotiate with the agent whether he will ship the goods directly or send them to you and then you will send them to the buyer. If you trust the goods of the agent, you can ask the agent to ship them directly, which saves a lot of time and postage.
