I don't control the price Amazon sells the book for anywhere in the world. It's interesting that the US price is $36.99 discounted on the US Amazon site to $26.63 but the Canadian price is listed as $37.13 with no discount. In contrast, the SSCP book has a US price of $59.99 discounted to $31.50 on the US Amazon site and the Canadian price is listed as $54.95 and is discounted to $34.45. The only difference I can identify is that I self-published the Security+ book through CreateSpace (a subsidiary of Amazon) while the other book is published through McGraw-Hill. I'm not sure who's getting that extra money, but it's not me. Perhaps Jeff Bezos and his investors. Due to a variety of reasons (and this just adds one more), I'll be publishing the book through another printer/distributor the next time. At any rate, good luck with the exam no matter what materials you use.
