Refunding shipping cost
Sometimes the cost of return shipping is your responsibility. For example, if you ship an incorrect or damaged product, you cannot deduct the original shipping or return shipping costs from the refund. You must provide a full refund to the buyer.
For more information, see Issue Refunds and Concessions for Seller-Fulfilled Orders.
For customer-fault returns, for example, accidental order or better price available, you can deduct the cost of return shipping from the refund. For more information, see Issue Refunds and Concessions for Seller-Fulfilled Orders.
To inform customers of the relevant details, update your return instructions:
From the Settings menu drop-down of Seller Central, click Return Settings.
Within Return Settings on the General Settings tab, scroll down to the Your return instructions input field and provide the following information to buyers: In some situations, buyers could be responsible for return shipping and any restocking fees that might be applicable. This amount can be deducted from your refund.
Click Save settings.
