First, decide which version you need: print or electronic. A printed book is an ordinary book. Electronic access to documents is through files on the SorokaM.com website; these files can be viewed and printed. The site is American, and works all over the world. (People buy from us in Vietnam, Uzbekistan, the USA, and other countries.) We accept payment by credit card and PayPal. The electronic version offers savings on shipping, for sure; but savings on printing are doubtful — printing on a printer, especially color, is very expensive. Calculate how much it will cost to print the entire book yourself vs. buying printed copies, especially considering that in some countries, delivery is free (to the USA, for example). But choose for yourself. I personally love regular books.
