Amazon returns are usually borne by the seller, but in special cases, the buyer may be required to bear part of the shipping costs. If the return is due to the seller's error or the product itself has quality problems, then the buyer does not need to pay any shipping costs for the return. However, if the buyer changes his mind or chooses not to like the product, then he may need to pay part of the shipping costs. There are detailed return policies and guidelines on the Amazon official website. Buyers are advised to carefully understand and confirm before returning the product.
