it may be that they want money..i come upon alot of sites like that, but what is the difference between buying their book they have advertised and buying a book you want to know about in a store? in their advertisment they lay out exactly what is in their book so you will know what youre getting and if youre interested then you buy it but if not youre in no way obligated to.. and if someone doesnt want to keep recieving emails from them you can always take them off your email list....and you wont recieve anymore emails, granted i dont know how things work in their country, but i dont blame them for wanting to promote their book in the usa, on the site they have many good referrals of the book by people and i for one was interested in it, and i got the book, granted it may have been 37 dollars but to me it was well worth it, i've gotten other books and this one was very clear to understand and it provided a step by step process for everything and included alot of useful spells as well, also included with the book are free books on meditation, devotionals, astral travel, and the greater key of solomon pts 1 and 2...and some others i cant think of at the moment..but i throughly enjoyed all the books and their information and some of their spells did wonders for me...
