Today I wanted to buy the new James Patterson book at Fictionwise (100% CC rebate), and I can confirm that using your regular creditcard (in my case a Dutch Visa card) with country USA does not work anymore. It seems they now check if the address that is used is a real USA address.
I was still able to use my Entropay virtual Visa card (
www.entropay.com). But I had to use an USA address. I used my Borderlinx (
www.borderlinx.com) mail forwarding address. But I expect that any valid USA address would work with the Entropay card.
I have had no problem using Micropay with country USA. but to get the credit card rebates it seems the Entropay card is the only solution for now.
