Who pays for return shipping?
The seller pays for return shipping if they offer a free returns policy or if the item was damaged, faulty, or doesn't match the listing description.

You pay for return shipping if you're returning the item because you changed your mind, and the seller's return policy states that buyers are responsible for return shipping.
