Having sold on evil-bay for years here are my 2 rules 1- don't sell anything that you have any money in, just time ( like car parts) 2- Give refunds promptly and let them keep the part.. it is not worth the headache trying to negotiate partial refunds etc. etc. Keep your feedback high at all cost and suck up the loss's. If you have anything worth anything use want ads or CL so you can control the interaction and not get hurt. Evil-bay is typical corporate culture..a great idea ruined by their greed.
