Just pay for it!!!!!
I honestly can not believe the level of morally bankrupt, freeloading, entitlement obsessed idiots that seem to use the Internet.
It doesn't matter if you don't like the price. You don't have to buy it. There is no need to own everything that is distributed over the Internet. Let's be honest if the family sold the book for 1p you'd still all be looking for the damn pirated torrent as people seem to have such a huge sense of entitlement that they see no reason anyone should be paid for anything and that the world owes them everything for free.
Would the same idiots that are promoting how to theive the book from the website do the same from a real shop? Imagine a small bookshop with rather weak security, i.e. no CCTV, no security and the cash desk is around a corner so that the owner can't see you. Would you steal the physical book if you felt it was over priced and fortunately (for you) poorly protected? I'm sure that 99% of people wouldn't. However, the Internet allows freeloaders a wonderful anonymity and a disconnected feeling from the onwer\retailer that allows them to ignore any feelings of guilt.
Should any of the freeloaders ever have the opportunity of making any money via the Internet then I hope their fellow freeloading brethren make sure this doesn't happen. There is, afterall, no honour amongst thieves.
@ Robert Long. Eric Oslo was not applying sixth former debating logic, but using a very sensible anology. You, however, seem to be blinded by some technological utopian ideal that just because it is computer based it needs to be worshipped like a Messiah and set free. DRM may prevent copying to varying extents, but "copying" is a method peculair to only a few products. An owner of a vase has no easy method of copying his vase (and then sharing the damn things with the world and his wife). Just because you can copy it on a computer doesn't mean that you have to. Sure the nature of digital media makes it difficult to prevent and it can't be undone; but again doing something just because you can doesn't make it OK.
