I've now released the book to Amazon, and Amazon Europe!
My preferred sales method is still through Createspace (also owned by Amazon), since you pay the same price but I get a significantly higher (about 30%) royalty there.
But if Amazon's easier for you, please use the link embedded here, since I get a kickback from Amazon while--again--you pay the same price.
Also, if you like the book, please give me a positive review on Amazon. Thanks!
