If the sender can not supply any tracking info you will get a full refund, Paypal just doesn?t take the sellers word that they sent it, if they did no one would use paypal ever, Even if the buyer had the chance to buy insurance but did not paypal will always come down on the side of the buyer if tracking info is not provide, this has happened to me about 3 or 4 times and I have always gotten my money back, Getting a refund usually takes a few weeks, as a seller when you get paid through paypal always use some kind of delivery confirmation so you don?t get ripped off.
