Thanks Major! Yes I added another CC I use regularly and it worked fine here.
But I still have a problem with a “prepaid” card, I did verify the zip code and it all checks out correct, and the card is “active” with funds per the site (Vanillagift - VISA). Maybe “debit /prepaid” CCs are getting kicked out in error by the processor here? It should work since I’m a US local and Gameflip is US based too. So it should act as a normal CC transaction.
Thanks again for looking into this. I’ll do some more double-checking.
