Ask for inactive account. Login on browser with VPN, and click pay with this card (whichever card you want to use). Take a screenshot, and every time you order, you can just scan the screenshot. It's not totally risk free, but it's much better IMO. Even if something goes wrong, you could always say you bought a gift card online, and all the seller sent you was a screenshot, or you could say that they sent you the card number and pin, and asked you to redeem it on your account. For a small balance, I highly doubt they would investigate into the issue and just let you go.
