I sold a leather garment on EBay to a buyer who lives on the other side of the world. The item was brand new, never worn and is made of a washed tumbled leather. The buyer is now complaining about some tiny marks on the item, which in my opinion is just part of the natural characteristic of the leather. She wants to return for a refund which is fine, but she's also expecting me to pay for the return shipping costs, which will be high. I've offered to pay for half, but where do I stand on this? She hasn't opened a SNAD case as yet, and I'm hoping to avoid that.
