Experience with freight agents in Pakistan

Before placing an order with a manufacturer, it's important to consider all aspects of the transaction, including shipping costs. In my previous orders, the air freight or shipping costs were reasonable, but this time they seem to be significantly higher. As a result, I am relying on the manufacturer to handle the shipping arrangements. However, I am open to suggestions and recommendations from others who may have experience with freight agent in Pakistan. I am also curious about the process and procedures involved in working with a freight agent and how they can help to negotiate lower shipping costs.
