A quick word about PP disputes:
They should only be used for: a.) non-receipt of goods purchased, b.) significantly mis-represented items.
Seriously-- if the watch looks like what was in the photo, and keeps some semblance of time, the buyer really does not have grounds to dispute it via PP. I can not even begin to tell you the number of transactions that I have conducted that did not satisfy me, but in the end, I received the watch and I did not ask enough questions.
Final though, PP is not stupid, and if investigated deeper can link many of us together. Imagine bringing down the house of cards over a $135 trinket. Something like this not only threatens the buyers account, but your account, and possibly others... Just sayin'...
