You can order some free islamic books from the following sites Insha'Allah:http://www.islamunveiled.com/eng/modules.php?name=Content&pa=showpage&pid=1
they are based in KSA and you can order 5 books from their list, totally free.
they are in Egypt, I think. They take a little bit longer than the above site, but Masha'Allah both are excellent.
May Allah grant them Firdaus for their efforts in dawah.
Do not worry about leaving your name and address, it is totally safe, but do it by pm for ImanWay (you have a choice, on the forum, or private message. I chose pm). And both sites always add one or two books without you asking.
enjoy your books when you receive them.
