Do I need to send the seller a pick-up code to exchange goods?

After the buyer agrees to exchange goods with the merchant, the pick-up code obtained after making an appointment to pick up the goods needs to be given to the courier who picks up the goods at home, and does not need to be sent to the seller.

Exchange means that the buyer communicates with the seller to negotiate the specific postage and exchange method. Both parties agree to exchange the goods, contact customer service, explain the exchange, choose the reason for the exchange, click Submit Application, and wait for the seller's consent. After waiting for the merchant to receive the return, it will resend the goods needed by the buyer, and the whole replacement process will be completed.
