Review the request and authorize the buyer to return the item to you. During the authorization process, you will be prompted to either use the RMA (Return Merchandise Authorization) number generated by Amazon or enter a custom RMA number of your own. RMA numbers will appear to the buyer on both the RMA and Return Mailing Label (RML). Amazon will send the buyer a non-prepaid Return Merchandise label that includes your return address. (See "Contact buyer" below for information on providing prepaid shipping labels.)
