Query: Definitely worth the price

While the books may now be available for free in the public domain (see the Gutenberg Project), this edition for the Kindle is well worth the cost for the formatting. I downloaded one of the books for free from Project Gutenberg and the formatting was all over the place on my Kindle. I then went and downloaded a sample of this version on my Kindle, and there is just no comparison for ease of reading. Sometimes what you get for free is not worth the price.
