If jdkaye is correct in that is the one on Amazon, you might think twice about that. First, the price claim is ridiculous and so is the claim that this is the claims that this version has "spectacular changes" - that's ridiculous. Like others have said you can download it yourself for free, or if you don't want to, I would suggest getting it from the "where to buy" link on this page at distrowatch:
That company seems to have a good reputation and has been a sponsor at distrowatch for some time, so I would assume we would have heard by now if they were not reputable.
Not trying to rain on your parade, but if you start from a bad copy, all will just be overwhelmingly confusing. Also, the latest version is 14.04.1 not necessarily a big problem, but it saves you from a whole lot of update downloading.
