Don't use ebay square trade mediator if a deal has gone bad on ebay.
Example: If an ebayer has left you a retalitory negative feedback and you contact square trade to try to get it removed they will charge $20.00 up front to mediate with the other party, BUT if the other party doesn't want to participate the case is closed automatically. POOF! your $20.00 is gone and of course it's non refundable. A buyer has no protection from paypal,ebay or square trade!
