Sellers have their own policies and procedures for returns and exchange. You must review your order carefully before placing it because all the products returns are given at the sole discretion of each Seller and a Seller may refuse to refund or exchange Products or errors a User made in their order.
If a Seller allows a return, then the User will need to follow the returns process outlined in the Seller Terms, or any other return procedures or processes described by the Seller from time to time.
