So I've been selling a few copies of my initial OSM map. Using Amazon's Kindle Direct Publishing, Amazon will pay me for sales from the USA Kindle Store with a USD checque, or electronically (EFT) if I have a USD denominated account. Living in Ireland, I have a Euro bank account, so I can't use EFT, and I also can't lodge a USD cheque to my euro denominated account! Likewise I can't use EFT for sales on Amazon.co.uk since it will be in GBP! I shall have to figure out a way to get paid, otherwise this wasn't such a clever business idea!
I will look at what other publishers on the Kindle Community Forums say, and see if there's some other way to get a USD account that can accept EFT (PayPal?).
