Egypt or any part of Africa through Kobobooks.com, I am told. I need somebody in Egypt to test this.
nb: you will have to convert the book to .mobi using a free software programme called Calibra if you want to read them using a Kindle device.
If you have problems let me know by commenting or emailing me so that I can send you a workaround.
You can always find details of availability and updates on the Catalogue page of this website.
If you live in Egypt please can you test the Kobobooks source and get back to me?
