For those ordering books...If you really need the book to arrive, I would be careful about ordering a used copy from the Amazon Marketplace sellers, the folks who sell their books online. Amazon the company obviously has a lot of experience and stake in making sure their products get to their destinations worldwide, paying whoever they need to pay if need be, to make sure their books get through. I ordered a used book from one of Better World Books allied sellers on Sept 1, and it never came. They are great about refunds, so I am out nothing, but sadly, I'm only out the book!
