First, you need to find a courier company with relatively cheap prices and negotiate with them about the price without a single order. Then you can collect the goods you sell together. The more the better. Then the courier company will come to your door. After the handover, they will print out the courier bill for you. After the packaging is done, it can be shipped directly. The premise is that your shipment volume must be large enough. If it is too small, the courier will not come to pick up the goods.
