i'm pretty sure that the paypal payment can be canceled by the payer before the reciever actually takes the money.

on a side note, since i've done ebay trading in a company before, if there's no tracking number, or postage invoice, the buyer can just say that he did not receive anything from your brother and u can do nothing about it because you have no proof that u gave him the xbox already!

in this case, you can give the police a call! (i'm serious)
