I recently got a new EVGA 3060 Ti secondhand from a fellow regular on another forum, for a non-scalper price even (he was in a queue but had bought a 3070 used in the interim). Anyway, I registered it with EVGA but what counts as a receipt for warranty purposes in such a case? I have an emailed payment receipt from Paypal, but there's no mention of the card there. The guy did send me a PDF of his original order from EVGA, but of course it has his name on it, and doesn't show me in any way. I have an email chain, I guess, but that's not one document. So I'm a bit at sea.
Would it be enough if he provided me a bill of sale acknowledging payment for his card on such and such a date? Would it need to be signed by him and scanned? Could I upload that plus my Paypal receipt (which itself does not mention the card)? Or, if I can upload two documents, I could use the PDF of his original order, then a PDF of my Paypal payment to him-- would that work?
