I’m an idiot. Make that a complete idiot.
Amazon.com do deliver to Yuzhno-Sakhalinsk, and indeed everywhere else in Russia. I am just incapable of reading an onscreen message. One of the books I was trying to order was out of print, and hence I was ordering it second hand through a third party affiliate of Amazon. This third party don’t deliver to Russia, hence a warning flagged up beneath this particular book as well as at the top of the page. Your clueless blogger saw a long list of books with a warning at the top and bottom and assumed the entire list was unable to be shipped to Russia.
As I said: idiot. Still, at least that’s an idiot with a book supply.
