StukaPTDear all,Thanks for your replies, I solved the issue by associating the bank account to my Paypal.Kind Regards.
polaroidik-terminology-Debit card - keyed to my primary bank account, paying with my own money from my bank account.Credit card - keyed to secondary bank account, paying with bank's money, expenses are monthly deducted from my primary account -answer-Standard debit and credit cards. Those are the types of cards i do use and have already tried. I do not use any "special" (prepaid/gift) or whatever single charge/purpose cards. I checked terms and the phrasing in link provided to EVGA store. There is a statement "EVGA does not accept the use of international- and prepaid credit cards linked to Paypal". This could explain a rejection for my international credit card. BUT this doesnt not explain rejections of regular international debit mastercards of mine. P.S.: I have initiated paypal balance refill. I was told that i would take roughly two days to see anything happening on paypal. Then i could try direct payment w/o card involved.
