Taobao clearance shop is credible.

It's genuine, but it's not sure whether it's good or not. I'm not sure if it's really customs clearance. You need to distinguish this by yourself. In order to report activities, some sellers may take the new mode to do clearance activities, saying that it is clearance, but it is not necessarily a real clearance.

However, it is generally impossible to provide you with a return service.
