having trouble donating?

Trying to donate to dodge the Que. I'm aware it says EU currency can I not use my us vista/MM from the us? i've tried and only got errors not really surprised. so would that subway gift card from the us work? I see a subway giftcard option. Thank for the help booboos =)

I've always gotten errors using Visa/Debit card, I would suggest using gift cards through the paymentwall system. Double check what gift cards they accept, and are available on the internet. I just got one last week for subway, and it worked instantly.
