My kids are selling some videos games on ebay. So far they have sold about a dozen. Saturday I received on of the envelopes back from the post office with everything but the video game in it. Apparently the envelope came open or ripped open and the game is not inside. I have submitted the claim form to the post office in hopes that they have the game but just don't know who it belongs to. I have also emailed buyer and let him know this. Should I give him the option of a refund? He paid shipping costs but did not opt for the insurance.
