It's because trying something for free is the best way of discovering it. And free doesn't mean sampling a quarter of a cookie - it means the whole cookie. It doesn't mean someone spraying my wrist with perfume - it means them putting a small bottle of the fragrance in my shopping bag. It means spending a weekend in a hotel and taking two showers using the same soap. It doesn't mean reading the first five pages of my book online - it means reading my whole book for free as a way of discovering me as an author.
I agree with the sentiment. Just not the method.
This guy got screwed:
What a colossal ripoff.
I went to the site, clicked the link, and I was required to give a lot of personal information (which I did). When I finally clicked the "download PDF" link, (after entering the free code) there was no PDF, only a 1 k file called "ebx.etd". NO PDF, NO BOOK.
So basically I just wasted a lot of time and gave away my personal information to your publishing company... FOR NOTHING.
Glad I didn't.
