Where can I order the book, Earthcore, at its cheapest price?

Question

Earthcore looks to be an amazing book, however on amazon.com it is listed at about forty dollars. This is way too much, I was looking and haven't found any cheaper source. I would like a reliable and well-known site. Thriftbooks for example, does a lot of business and is reliable, I do not want to order from a site that isn't reputable. Thanks

Answer 1

seems like the going price, checked ebay, half.com and a few others all in the same range. must be a good book
