What are some things that I can proactively do to ensure that I would win a bogus PayPal dispute if a buyer were to try to say that I sent them an item that was not as described? So far what I plan to do is: 1) Have UPS package it themselves and write serial # on receipt 2) Have photos of the device's condition before I sent it. Not sure how either would help me as far as proving that the device I sent was in like new, working condition. Is there anything else I can do? Also, the buyer who purchased my iPad has paid via PayPal in full but has 0 feedback on eBay and according to PayPal: "(The sender of this payment is Unregistered)", but it does say that the buyer's address is a "Confirmed Seller Protection address" and it is a U.S. address. Should I have any concerns? Thanks.
