So, a few weeks ago I sold a $32 lot of cards, nothing major, but I am curious what everyone's opinions are. I shipped with tracking and it says "delivered, left on porch or doorstep." Buyer opened a claim today saying he never received the cards. Is there any way I can win this or prove anything or am I going to have to refund the money? I know I am responsible for making sure the item is delivered, so I'm guessing that means all the way to the buyer's hands?

Thank you in advance.
