I have added ordering links to the Canadian, British, French, German and Japanese branches of Amazon.com to my "Elephants of Style" and "Lapsing Into a Comma" pages.
Bonus content: Note that I used "Elephants of Style" in an adjectival reference to "The Elephants of Style." Nothing wrong with that; in fact, it's preferable. For a related reason, don't go capitalizing the in something like "the Hague-based International Court of Justice," even if you normally cap The Hague. In that instance, the goes with International Court of Justice, not with Hague.
