I've been able to successfully use my Banco Progreso Amex debit card with eBay and Amazon, but not with iTunes. Same also goes with my BHD credit card. I want to keep my iTunes account in the US store, although I don't even know if there's a Dominican iTunes store.
I think the only option I have right now is to buy a gift card off eBay and have them email me the code.
