also a worthwhile note, cause I actually called paypal to inquire about this today as I wasn't sure myself..
they said this:
1 - domain payments are treated like any other digital good payments.. ebooks etc..
so they do recognize domain payments, what you need to make sure buyer does is selects no shipping address when paying for goods. this tells them its a digital transaction. and its a crucial part of their investigation afterward.. that there be no shipping address present. it can make all difference they told me. they also said its best to create invoice for buyer, and not have them send you money. this way in invoice you can add specific note and details about transaction. like saying it is only ownership transfer and no goods are present or refunds offered.
that's for "payment for goods" chargeback can still be filed, and depending on reason type, they will fight it for you. they will not fight it though if for instance shipping address is present etc. so remember that part they said.
2- .....now about payment for domains as "family friends payment"
no protection offered, BUT they said 9/10 times, they will reject all credit card chargeback claims, as this is clearly a personal payment type. their words not mine.
and lastly:
ideal way to not get chargeback is ask for echeck/bank funded payment. even if takes few days to clear. or simply to pay using paypal balance. can ask for screenshot of paypal balance as proof too from people you do not know. it can fail, be faked at last minute etc.. but it's better than nothing imo.
so those are the things I do to minimize risks. hope to help.
cheers
