I have answered yes to all of these at various points in the past, but no longer :-)
Ancient Faith Ministries now have an up-and-running e-bookstore with a superb selection of books which can be purchased and delivered immediately to your e-reader no matter where in the world you might be. Books are available in a variety of formats - mobi, epub or pdf, (though not all titles will have every format available at the moment) so the books will generally be suitable for Kindle, Nook, Kobo or generic e-readers. Purchasing and downloading books is simple and straightforward, and if you have any problems, staff running the site will do their very best to assist you to resolve them quickly. I was able to navigate the site, purchase and download my book with no problem at all.
Currently, the 55 books in the e-book catalogue are available for $8.99 per title. I'm reading and thoroughly enjoying "The Scent of Holiness: Lessons from a Women's Monastery" by Constantine R. Palmer at the moment and have spent quite a while looking at the titles to see which one I will read next.
I am particularly impressed by the fact that once you have purchased and downloaded your book, you can lend it to someone or even sell it once you have read it, provided that you do not retain a copy for yourself as well. (http://www.orthodoxchristianebooks.com/copyrights-and-usage/)
We really are spoilt for choice now, and all I can say to Ancient Faith Ministries is a huge "Thank You!" for making this possible.
