1. If the goods you buy on Taobao are free shipping, the seller will usually specify the courier company to cooperate with. If the courier company the buyer wants is within the scope of the seller's courier companies, free shipping is still available. If the courier company you choose is not within the scope of the seller's cooperation, the buyer needs to make up the price difference. The buyer can choose at will.

2. If the courier is not free shipping, under normal circumstances, the courier can be specified by the buyer at will, but the price will be relatively expensive, because the seller does not have any cooperation, so it needs to be calculated according to the original price of the courier.
